The Linux Emacspeak HOWTO Jim Van Zandt, jrv@vanzandt.mv.com v1.4, 21 Dececember 1997 This document describes how a blind user can use Linux with a speech synthesizer to replace the video display. It describes how to get Linux running on your own PC, and how to set it up for speech output. It suggests how to learn about Unix. ______________________________________________________________________ Table of Contents 1. Introduction 2. Stage 1.

Legalese ______________________________________________________________________ 1. Introduction Emacspeak is an Emacs subsystem that allows the user to get feedback using synthesized speech. Screen reading programs allow a visually impaired user to get feedback using synthesized speech. Such programs have been commercially available for well over a decade. Most of them run on PC's under DOS, and there are now a few screen-readers for the Windows platform. However, screen-readers for the UNIX environment have been conspicuous in their absence. This means that most visually impaired computer users face the additional handicap of being DOS-impaired -- a far more serious problem:-) Emacspeak is an emacs subsystem that provides basic speech access. Emacspeak will always have the shortcoming that it will only work under Emacs. This said, there is very little that cannot be done inside Emacs, so it's not a real shortcoming:-) Within Emacs, you can open a "shell window" where you can run commands and examine their output, even output which has scrolled out of the window. Emacs provides special modes for running certain commands. For example, it can parse error messages printed by a compiler and open a separate edit window with the cursor at the point of the error. It can also run a debugger and keep a separate edit window open at the point in the source code corresponding to the program counter. Emacspeak does have a significant advantage: since it runs inside Emacs, a structure-sensitive, fully customizable editor, Emacspeak often has more context-specific information about what it is speaking than its commercial counterparts. In this sense, Emacspeak is not a "screenreader", it is a subsystem that produces speech output. A traditional screen-reader speaks the content of the screen, leaving it to the user to interpret the visually laid-out information. Emacspeak, on the other hand, treats speech as a first-class output mode; it speaks the information in a manner that is easy to comprehend when listening. This initial version provides a basic speech subsystem for Emacs; using Emacs' power and flexibility, it has proven straightforward to add modules that customize how things are spoken, e.g. depending on the major/minor mode of a given buffer. Note that the basic speech functionality provided by Emacspeak is sufficient to use most Emacs packages effectively; adding package-specific customizations makes the interaction much smoother. This is because package-specific extensions can take advantage of the current context. Emacspeak will only work with emacs. However, emacs can be used to run any program that has a command-line interface (ls, cd, rm, adduser, etc.). You can even run those like less or lynx which use escape sequences to control the appearance of the screen. The key to this is eterm mode, which you get with the emacs command M-x term. Emacs is a large program, but it does not all have to be in RAM, because Linux has virtual memory. You can designate a swap partition, so that programs (or parts of programs) can be swapped out when they are not being used. You can comfortably run emacs with 8 MB of ram plus 8 MB of swap space. This document is limited to the following: o Linux (not Free BSD) o The Slackware distribution (not Red Hat, Debian, etc.) o Speech output only (not Braille - see the Access HOWTO) o DECtalk (Dectalk Express and MultiVoice), DoubleTalk, and LiteTalk synthesizers (--not the Accent, SmarTalk, a sound card, etc.) o Use of Emacs, with T. V. Raman's Emacspeak package, to drive the synthesizer. The use of adaptive technology with Linux, and in particular, using adaptive technology to make Linux accessible to those who could not use it otherwise, is covered in the Linux Access HOWTO. If you would like to help extend this document to cover one or more of the other alternatives, or point me to a discussion somewhere else, please contact me. Emacspeak was written by T. V. Raman raman@adobe.com. Emacspeak has a Web page at <http://www.cs.cornell.edu/Info/People/raman/emacspeak/emacspeak.html>. Emacspeak supports several speech synthesizers. The software required depends on which you have. If you have a DECtalk Express or Multivoice, you need the basic Emacspeak package, tcl (an interpreter), and tclx (extensions for tcl). You can get the source package for Emacspeak from the Emacspeak web page, or a binary package in one of the popular distributions of Linux (Slackware, Red Hat, or Debian). I build each of these packages. Since I normally run Debian, the Debian package will be available a little sooner than the others. At this writing, the most recent release of Emacspeak is version 7.0. Here are some URLs: <http://leb.net/pub/blinux/emacspeak/cornell.mirror> <ftp://leb.net/pub/blinux/emacspeak/blinux/emacspeak-6.0-2.i386.rpm> Note: there are European mirrors of the blinux site which you should use if they closer: <ftp://ftp.uni-muenster.de/share/public6/> <ftp://ftp.gwdg.de/pub/linux/misc/blinux/> For the external DoubleTalk or LiteTalk synthesizers, you need the Emacspeak package and a separate driver which comes in the emacspeak- dt package: <ftp://leb.net/pub/blinux/emacspeak/blinux/emacspeak-dt-0.27.tar.gz> <ftp://leb.net/pub/blinux/emacspeak/blinux/emacspeak- dt-0.27-1.i386.rpm> <http://www.mv.com/ipusers/vanzandt/emacspeak- dt_0.27-1_i386.deb> For the internal DoubleTalk, you need three pieces of software: the basic Emacspeak package, the emacspeak-dt package, and a device driver. Here are some URLs for the device driver: <ftp://leb.net/pub/blinux/emacspeak/blinux/dtlk-1.12.tar.gz> <http://www.mv.com/ipusers/vanzandt/dtlk-1.12.tar.gz> <http://www.mv.com/ipusers/vanzandt/dtlk_1.12-1_i386.deb> There is an alpha test version of a driver for the Braille 'n Speak, Braille Lite, and Type 'n Speak devices used in "speech box" mode: <ftp://leb.net/pub/blinux/emacspeak/blinux/emacspeak-bs-0.3.tar.gz> Computer hardware, Unix user commands, Unix system administration, Emacs, and Emacspeak are each substantial subjects. Attempting to learn all of them at once is likely to lead to frustration. Instead, I suggest that the new user go through a sequence of stages, learning about only one system at a time. 2. Stage 1. DOS with speech Most blind computer users have speech synthesizers with a screen reader program like JAWS [``JAWS'']. (References in this format refer to entries in the "Footnotes and References" section below.) Using this setup, install and become familiar with some terminal emulator like Telix [``TELIX''] or Commo [``COMMO''], which are available from the SimTel archive [``SimTel''] among others. 2.1. Getting Linux on CDROM If you have or can borrow a CDROM drive, I recommend you get one of the many good distributions of Linux on that medium. The instructions below are for the Slackware distribution. I am most familiar with disks from InfoMagic [``InfoMagic'']. Another source is Walnut Creek [``Walnut Creek''] (where the whole idea of inexpensive CDROMS full of programs from Internet archives got its start). Distributions other than Slackware are available from Red Hat [``Red Hat''], Craftwork [``Craftwork''], and Yggdrasil [``Yggdrasil'']. As a rule, these CDROMS use the "ISO 9660" format, which can be read under DOS. (They also use the "Rock Ridge extensions" which add extra files in each directory. Linux uses the extra information to give you long filenames, both upper and lower case characters in filenames, and file permissions.) 2.2. Getting Linux by FTP Another way to get Linux and its documentation is by FTP over the Internet. The home site for the Slackware distribution is Walnut Creek [``Walnut Creek'']. It is also carried by sunsite and many of it mirror sites. Here is a partial list: o USA (home site) <ftp://ftp.cdrom.com/pub/linux/slackware> o UK/Europe <ftp://src.doc.ic.ac.uk/public/Mirrors/ftp.cdrom.com/pub/linux/slackware-3.1> o Japan <ftp://ftp.cs.titech.ac.jp/pub/os/linux/slackware> o Taiwan <ftp://NCTUCCCA.edu.tw/OS/Linux/Slackware> o Hong Kong <ftp://ftp.cs.cuhk.hk/pub/slackware> o USA <ftp://sunsite.unc.edu/pub/Linux/distributions/slackware> o USA <ftp://uiarchive.cso.uiuc.edu/pub/systems/linux/sunsite/distributions/slackware> More sites are listed in the INFO-SHEET: <http://sunsite.unc.edu/pub/Linux/welcome.html> <ftp://sun- site.unc.edu/pub/Linux/docs/HOWTO/INFO-SHEET> <ftp://uiarchive.cso.uiuc.edu/pub/systems/linux/sun- site/docs/HOWTO/INFO-SHEET> 2.3. Linux Documentation Read the Linux documentation. I will quote here the file names and locations on the first disk of InfoMagic's December 1996 "Developer's Resource" set of six CDROMS, as seen under DOS. Other CDROM sets should have similar information, though perhaps differently arranged. The Slackware distribution is on disk 2 of the set. Matt Welsh's step by step guide to installing Slackware is in \doc\install-\install-.002. (This is a 245 page book!) More general information is in the Linux "Frequently Asked Questions" list in \docs\linux.faq\linux-fa.asc. Longer descriptions are in "HOWTO" documents (of which this is one). They are found in \docs. Note particularly \docs\hardware, which lists which kinds of hardware are supported by Linux, \docs\meta-faq, which points to sources of information (that is, a more extensive version of this paragraph), and \help\index, which is a list of the HOWTO documents with short descriptions. The Linux installation HOWTO, \docs\installation, is another (much shorter, somewhat older) version of Matt Welsh's installation instructions. One note on reading the documentation. You may run into files with ASCII highlighting, where character-backspace-character stands for "bold", and underscore-backspace-character stands for "italics". One way to handle this is to use the less program, which displays these sequences in alternate colors. A DOS screenreader can, for example, search for such highlighted text. A DOS version of less can be obtained by FTP from the SimTel archive [``SimTel'']. Within the SimTel collection, look for directory msdos/textutil. For example, try <ftp://ftp.coast.net/pub/SimTel/msdos/textutil>. I will suggest four alternatives for learning Emacs commands (see section [``Learning Emacs'']). The first option is to install Emacs under DOS and learn it while using the DOS screen reader. Where to get Emacs for DOS is a "frequently asked question" [``Emacs for DOS'']. The source code for Emacs (about 10 MB) can be gotten from <ftp://prep.ai.mit.edu/pub/gnu/> (look for emacs-19.34b.tar.gz or similar), or from one of many mirrors of the GNU collection [``Gnu Mirrors'']. 3. Stage 2. Terminal to remote UNIX system Arrange for what is called a "shell account" on some Unix system. Most Internet Service Providers (ISPs) can provide this service. Use the terminal emulator program and a modem to dial in. Learn the basic Unix commands. If the system has Emacs installed, or you can persuade the system administrator to install it, this is your second chance to learn it. It is probably best to learn it at this point, because administering a Unix system (the next stage) will call for you to edit files. Therefore, I include here my suggestions for learning both Unix and Emacs. 3.1. Learning Unix When you arrange for a shell account, or set up a new account on your own machine, you will have to decide on a username and a password. Your username will also be used in your email address, so try to find something short and memorable. Your password is important, and should be hard to guess. That usually means at least six characters, including at least one non-alphanumeric character. When a Unix system is ready for you to log in, it normally displays a prompt ending with "login:". At this point you should type in your username. It will then prompt you for your password, and will turn off command echoing while you type it in. The command to finish a terminal session is logout. To learn about a command, use the man command to type its manual page ("man page" for short). For example, to learn more about the cp command by typing man cp. Of course, this helps only if you know or can guess the command name. However, each man page has a line near the beginning with the command name and a short description of what the command does. You can search a database of these lines using the command apropos. Thus, typing apropos working will list lines that include the word "working". Here's what that command prints here: cd (n) - Change working directory pwd (n) - Return the current working directory Cwd (3pm) - get pathname of current working directory chdir (2) - change working directory fchdir (2) - change working directory get_current_dir_name (3) - Get current working directory getcwd (3) - Get current working directory getwd (3) - Get current working directory pwd (1) - print name of current/working directory rcsclean (1) - clean up working files The numbers in parentheses are sections of the manual. User commands are in section 1. Functions called from within programs are in sec- tions 2 and 3. Commands used mostly by the system administrator are in section 8. You can find out more about the on-line manual with the command man man. Under Unix, commands normally accept options starting with a minus sign rather than the forward slash used under DOS. In a path, directory names are separated by forward slashes rather than backward slashes. Both operating systems have a "standard input", by default the keyboard, and a "standard output", by default the display screen. You can redirect the standard input using "<", and redirect the output using ">". You can use the output from one command as the input of another by separating the two commands with "|". This is called the "pipe" symbol. The program that interprets your command is a "shell". Under DOS, COMMAND.COM is the shell. Most Unix shells are decendents of either the Bourne shell sh or the C shell csh. The shell most commonly used with Linux is the "Bourne again shell", or bash. It has several features which can reduce the need for typing. You can use the cursor up key key to bring previous commands to the command line. The cursor will be at the end of the command. You can use cursor left and right to move the cursor within the command, and edit it with Emacs style commands (control-D or DEL to delete the character to the right, et cetera). Also, you can insert the last word in the previous command with ESC-. (escape period). You can learn about these and other commands from the bash man page, in the section entitled "READLINE". If a program gets "stuck", here is a sequence of keystrokes to try: o Control-Q. You may have sent a control-S, which halts all output, without realizing it. The control-Q will restart it. o Control-D, which signals "end of file" under Unix (similar to control-Z under DOS), in case the program expects input which you are not prepared to supply. o Control-C is an interrupt, which may halt the program. o Control-Z puts the program in the background. At this point you may simply log out, although you will be warned about the background process and will have to repeat the logout command. You can instead kill the process, as follows: Run ps with no arguments. It will list a header line, then one line for each of your processes. The first item on each line is the process id number, or PID. The command used to start the process (or at least the beginning of it) appears at the end of the line. If the PID were 117, you would kill the process with the command kill -9 117. o If running Linux from the console, alt-2, or some other alt-number combination, will switch to a different virtual console. You can log in there just as if you had sat down to a different terminal. o If your machine is connected to a network, you can log in from another machine. o Control-alt-del should reboot the computer nondestructively. o As a last resort, you can hit "reset" or cycle the power. This will leave the filesystems in an invalid state, since some buffers will not have been written to disk. The kernel will discover this while booting, and will take time to check and repair the filesystems. Actual data loss is unlikely unless you had something else going on at the time. Guido Gonzato Guido@ibogfs.cineca.it has written an excellent guide to Linux for (former) DOS users, the DOS2Linux mini-HOWTO. You can probably find it where you found this document, or else at <ftp://sunsite.unc.edu/pub/Linux/docs/HOWTO/mini/>. You can find general Unix information, including manual pages for several systems at <http://www.cis.ohio- state.edu/hypertext/man_pages.html> There is a tutorial entitled "Beginning Unix and the C Shell" at <http://www.eng.hawaii.edu:80/Courses/C.unix/page-03.html>. You can get general help from <http://www.nova.edu/Inter- Links/UNIXhelp/TOP_.html> or <http://www.eecs.nwu.edu/unix.html> You can find a list of books on UNIX at <http://www.eskimo.com/~cher/eskimospace/booklist.html>. 3.2. Learning Emacs When you start Emacs, you will normally list on the command line one or more files which you will be editing. To edit a file named "foobar" with Emacs, you would enter the command emacs foobar. If you enter the command emacs with no arguments, GNU Emacs will print out an introduction which includes the first five commands you need to learn, approximately as follows: Type C-h for help; (`C-' means use CTRL key.) Type C-x u to undo changes. Type C-h t for a tutorial on using Emacs. Type C-h i to enter Info, which you can use to read GNU documentation. To kill the Emacs job, type C-x C-c. Note the way Emacs documentation refers to key combinations. C-h means hold the control key down while typing "h". You will also run into key combinations like M-v, which is pronounced "meta v". The tutorial suggests holding down the key labeled "edit" or "meta" then typing "v". I have never run across a keyboard with those keys, so I always use the escape key instead: typing "Esc" then "v" (two separate keystrokes). After using Emacs for a long time, I discovered that under Linux, the left "Alt" key works like a "meta" key. You may want to use this. On the other hand, some of these key combinations may conflict with your screen reader or communications program under DOS. Using the escape key is more reliable. Three of the above commands start with C-h, which may be treated as a backspace by your communications program. In that case, you may access the help command using the long form M-x help. Conversely, you may find that pressing the backspace key starts the help command. This issue is treated in the Emacs FAQ, which is available within Emacs using C-h F or M-x help F. Look for the question "Why does the `Backspace' key invoke help?". In the mean time, you can end the help session with the command C-g. (This is the keyboard-quit command, which cancels any prefix keys you have typed.) You may also find that C-s and C-q are unavailable because they are used for flow control (XON and XOFF). You should look at the question "How do I handle C-s and C-q being used for flow control?" in the FAQ. For the particular command C-x C-s (save buffer), you may substitute the command C-x s (save-some-buffers). The former command saves the current buffer, while the latter asks the user about each of the modified buffers. Note in particular the command "C-h t" to start the Emacs tutorial. That is one the first things you will want to try. I will only make a couple of comments on the tutorial. To move the cursor, it gives the four commands C-f, C-b, C-p, and C-n (for forward, back, previous line, and next line). These commands always work. However, with a properly installed Emacs, the regular arrow keys should also work. Try them out and use them if you are more comfortable with them. Similarly, you may be able to use home, end, page down, and page up keys in place of the standard commands C-a, C-e, C-v, and M-v. Finally, all Emacspeak commands begin with C-e. Once you start using Emacspeak, you will have to type it twice to get the end of line function. (The "End" key should be unaffected by Emacspeak.) 4. Stage 3. Terminal to local Linux system This arrangement again requires a DOS machine with a speech synthesizer and a terminal emulator program. However, instead of dialing up a remote computer, it is used as a terminal to a local computer running Linux. To get to this point, you need to install Linux on a machine. You may be able to prevail on a knowledgable friend to help you with this. However, it is also possible to install it yourself with speech feedback for almost the whole procedure. 4.1. Installing Linux First, some background. Even the simplest Unix system requires a program called the kernel and a root file system. The kernel has all the device drivers and resource management functions. One normally thinks of a "file system" as residing on a hard disk or floppy disk, but during an installation it is usually in ram. Linux is normally installed by writing a kernel image to a floppy disk, called the "boot floppy", configuring it to reserve a section of RAM for a ramdisk, then filling that ramdisk with data from a second floppy disk, called the "root floppy". As soon as both floppies have been read in, the user can log in as "root" and complete the installation. The sighted user logs in on the "system console", that is, the computer's own keyboard and video display. However, remember that Unix has been a multiprocessing operating system from the very beginning. Even this very primitive Unix system, running out of a small ramdisk, also supports logins from a terminal connected to a serial port. This is what a blind user can use. To connect the two computers, you can use a "null modem", a serial cable that connects ground to ground, and transmit on each end to receive on the other. The cable that comes with the DOS application LapLink will work fine. It is particularly handy, in fact, because it has both a 9 pin and a 25 pin connector on each end. If you want to check a cable or have one made, here are the required connections: For two 9 pin connectors, connect pin 2 (receive data) to pin 3, pin 3 (transmit data) to pin 2, and pin 5 (signal ground) to pin 5. For two 25 pin connectors, connect pin 2 (receive data) to pin 3, pin 3 (transmit data) to pin 2, and pin 7 (signal ground) to pin 7. For a 9 pin connector (first) to a 25 pin connector (second), connect pin 2 (receive data) to pin 2 (transmit data), pin 3 (transmit data) to pin 3 (receive data), and pin 5 (signal ground) to pin 7 (signal ground). You may have noted that I have included no connections for the "handshaking" signals. During login, the serial port is handled by the program agetty. Recent versions of this program accept a -L switch which tells it not to expect modem control signals. The version in Slackware 3.0 does, but the one on the 3.0 (and earlier) installation root disks does not. However, Pat Volkerding has assured me that the root disks in the next release of Slackware will have the updated version of agetty. It is also possible to use the earlier root disks [``Emacspeak with Earlier Slackware Releases'']. Consult the documentation on your CDROM, or downloaded from an FTP site, and choose a boot disk with the proper kernel features for your hardware (IDE or SCSI, CDROM driver, etc.). I have the InfoMagic September 1996 "Developer's Resource" set of six CDROMS. Slackware 3.1 is on disk 1 of that set, mostly in the two directories slackwar and slakware. (Note the difference in spelling. You will access them in alphabetical order: first slackwar, then slakware.) Documentation on the boot floppies is in \bootdsks.144\which.one. A copy of the DOS program for writing boot images to a floppy, rawrite.exe, is in the same directory. Assuming the cdrom is the M drive under DOS, one might use these commands to write to a floppy disk in the A drive: C>m: M>cd \bootdsks.144 M>rawrite scsinet.s a: Similarly, to write the "text" root disk: C>m: M>cd \rootdsks M>rawrite text.gz a: If you install from floppies, you should also copy the Emacspeak package onto a floppy with a command like this: C>copy m:\contrib\emacspea.tgz a: For the actual installation, proceed as follows: Use the null modem to connect the computer running DOS and equipped with speech output (which I will call the "DOS machine") to the computer into which you want to install Linux (the "Linux machine"). Boot the DOS machine, and start your terminal emulation program. Set it up for 9600 baud, no parity, eight data bits, 1 stop bit. On the Linux machine, insert the "boot" disk and boot (power up, cntl- alt-del, or hit the reset switch). It should read the disk for five seconds or so, beep, and stop with the following text: (Note: in the following, the large blocks of text quoted from the installation disks are preceded by "-- begin quote" and followed by "-- end quote". To skip to the end of a quote, you may search for two dashes starting in the first column. I have word wrapped some sections to limit the line lengths.) -- begin quote Welcome to the Slackware96 Linux (v. 3.1.0) bootkernel disk! If you have any extra parameters to pass to the kernel, enter them at the prompt below after one of the valid configuration names (ramdisk, mount, drive2) Here are some examples (and more can be found in the BOOTING file): ramdisk hd=cyl,hds,secs (Where "cyl", "hds", and "secs" are the number of cylinders, sectors, and heads on the drive. Most machines won't need this.) In a pinch, you can boot your system with a command like: mount root=/dev/hda1 On machines with low memory, you can use mount root=/dev/fd1 or mount root=/dev/fd0 to install without a ramdisk. See LOWMEM.TXT for details. If you would rather load the root/install disk from your second floppy drive: drive2 (or even this: ramdisk root=/dev/fd1) DON'T SWITCH ANY DISKS YET! This prompt is just for entering extra parameters. If you don't need to enter any parameters, hit ENTER to continue. boot: -- end quote I have almost always been able to just hit "enter" at this point. After your entry, the Linux machine should read the floppy for another twenty seconds or so, then boot the kernel. The first thing it prints is "Loading ramdisk...", which is somewhat misleading. In this case, "ramdisk" is actually the name of the kernel configuration. Each device driver in the kernel displays a line or two. The particular disk I'm using (the "bare.i" bootdisk) displays more than one screen's worth. It is possible to type shift-page up to scroll the text back. On my machine, the boot messages are as follows: -- begin quote Loading ramdisk..... Uncompressing Linux...done.

It is also recommended that you create a swap partition (type "Linux swap") prior to installation. Most users can use the Linux "fdisk" utility to create and tag the types of all these partitions. OS/2 Boot Manager users, however, should create their Linux partitions with OS/2 "fdisk", add the bootable (root) partition to the Boot Manager menu, and then use the Linux "fdisk" to tag the partitions as type "Linux native". If you have 4 megabytes or less of RAM, you MUST ACTIVATE a swap partition before running setup. After making the partition with fdisk, use: mkswap /dev/<partition> <number of blocks> ; swapon /dev/<partition> Once you have prepared the disk partitions for Linux, type "setup" to begin the installation process. You may now login as "root". slackware login: -- end quote The program that prints the login prompt is called agetty. The Slackware 3.1 root disks are set up to allow logins only from the computer's own keyboard. You will have to reconfigure it to also allow logins from a serial port. This requires typing four lines on the Linux machine keyboard, with no voice feedback. If you realize you have made a mistake before hitting the carriage return, you can erase it with the backspace key. You can also discard what you have typed on a line with control-C. Here is what you type: root cat >>/etc/inittab s1:45:respawn:/sbin/agetty 9600 ttyS0 control-D init q I will repeat that with explanations of what is going on. First, type "root" and a single carriage return to log in (no password is needed). Next, you need to append one line to /etc/inittab. Type the following two lines: cat >>/etc/inittab s1:45:respawn:/sbin/agetty 9600 ttyS0 Finish each line with the "enter" key. Then type a control-D, which signals end of file to a Unix program. (Note: In the second line, the next to last character is an upper case "S". Everything else is in lower case.) This adds a line to the configuration file of the program init, to instruct it to use agetty to watch for logins on the first serial port on the Linux machine, called "COM1" under DOS, or "/dev/ttyS0" under Linux. To use the second port instead, change the last item on the above line to "ttyS1". Then type init q which causes init to reread /etc/inittab. At this point the DOS machine should display the login prompt (the third of the blocks of text quoted above). On the DOS machine, type root, and finish the installation. (The next thing you should do is create and enable a swap partition.) If you don't get the Slackware installation disk prompt, try the following: o Type a single carriage return on the DOS machine. o Recheck the terminal setup (9600 baud, no parity, eight data bits, 1 stop bit) o Disconnect the null modem from the DOS machine. In its place, connect a modem which supports the Hayes "AT" commands. Type AT and a carriage return. You should get a reply of "OK" from the modem. Once you get the above prompt on the DOS machine, you may type root and a carriage return to log in, and complete the installation like any other user. Of course, you must remember to include these packages: emacs, tcl, and tclX. The installation script will offer to prepare a boot floppy. You should do this, since it is the most foolproof way to boot Linux. You will probably also want to install lilo (which is an abbreviation for "Linux loader") and/or loadlin (which is an abbreviation for "load Linux"). The installation script can install lilo. Loadlin is a DOS program that will let you boot from DOS to Linux. Install it on a DOS partition, and copy a compressed kernel file (usually named zImage) to the same partition. While running DOS, you may boot Linux with a command like loadlin zimage root=/dev/hda3 ro/. (I have assumed here that the kernel image is in the same directory as the loadlin program. You may find it more convenient to store kernel images in subdirectories named for the kernel version.) After the Slackware setup script finishes the main installation, it will tell you to restart by pressing cntl-alt-del. Before doing that, you should install emacspeak. It can be found with the other "contributed" software. In the InfoMagic set, it is in slackwar/contrib. Assuming you are installing Linux directly from a cdrom, the setup script will mount the cdrom under /CDROM, and you may install emacspeak with the following command: # installpkg /CDROM/slackwar/contrib/emacspeak.tgz If you install from floppies, insert the floppy you made earlier and type this: # mount -tmsdos /dev/fd0 /floppy # cp /floppy/emacspea.tgz /tmp/emacspeak.tgz # installpkg /tmp/emacspeak.tgz You should not install the package directly off the floppy disk, because the DOS filesystem will not allow the full filename, so the installpkg program will think the package name is "emacspea" and will store its records under that name. If you have a DoubleTalk or LiteTalk speech synthesizer, you should also install the emacspeak-dt package. Reboot the Linux machine with the new boot floppy, with the DOS machine still connected. You should get a login prompt on the DOS machine. Celebrate! After getting this system working, you need to learn emacs (third option) and Unix system administration. 4.2. Learning Unix System Administration Mostly you will learn system administration as the need arises. First adding a user (yourself), then installing programs, and so forth. The exception to this is making backups, which you should learn before you need them. Among the many programs you will need to learn are these: adduser Register a new user, including creating a home directory and adding an entry in /etc/passwd. tar Create and unpack .tar files, which are collections of files (something like .zip files). To list the contents of an archive, use tar -tf foobar.tar. For a more verbose listing, use tar -tvf foobar.tar. To unpack an archive, use tar -xf foobar.tar. chmod Change permissions of a file or directory. chown Change ownership of a file or directory. find Search directories recursively. For example, the command find . -name '*alpha*' -print means: search starting in the current directory (.) for a file whose name contains the string "alpha" (-name '*alpha*'), and print its path and name (-print). (With GNU find, the -print is optional.) du Display the amount of space occupied by files or subdirectories. For a file with "holes", this may be much less than the length of the file. df Display filesystem capacities, free space, and where they are mounted. mount Display filesystems, where they are mounted, and the mount flags. ifconfig Configure and check internet protocol (IP) network interfaces, including Ethernet cards, SLIP links, and PLIP links. route Configure and check IP network routing, after the interface is configured. ping Check IP network connectivity, after the interfaces and routes are configured. ftp Transfer files across the Internet. Here are some programs you may want to install: agrep Approximate grep searches for approximate, not exact, string matches (also called "fuzzy string searches"). archie Search Internet archives for files. flip Convert text files between Unix and DOS formats. glimpse Fuzzy string searches in large collection of files (uses agrep). lynx Text mode web browser. Here are some Web pages related to Unix system administration: General information <http://www.ensta.fr/internet/unix/sys_admin/> or <http://www.sai.msu.su/sysadm.html> There is a Unix system administration tutorial at <http://www.iem.ac.ru/sysadm.html> UnixWorld Online Magazine Home Page <http://www.wcmh.com/uworld/> Internet Essentials for UNIX System Administrators Tutorial <http://www.greatcircle.com/tutorials/ieusa.html> Pointers to Unix goodies available on the Internet <http://www.ensta.fr/internet/unix/> Pointers to Unix system administration "goodies" available on the Internet <http://www.ensta.fr/internet/unix/sys_admin/> 5. Stage 4. Emacspeak under Linux The Slackware setup script for Emacspeak should create the needed environment variables and install a script emacspeak that starts emacs with emacspeak. This is your fourth option for learning Emacs. This is the first time you will be able to actually use Emacspeak. A short tutorial appears below. Within Emacs, you may type C-h C-e to get a list of the commands. To search for a command, use C-h a. To get an explanation for a key sequence, use C-h k. There is also an info file which is part of the Emacspeak distribution. Within emacs, you may type C-h i to open the directory to the info pages. Search for the emacspeak menu item by typing C-s emacspeak, then two carriage returns (one to terminate the search, and a second one to go to the info page. If you have the standalone info program installed, you can consult the info file with the command info Emacspeak. 5.1. Emacspeak Introduction - Speech Enabled Normal Commands All of the normal Emacs movement commands will speak the relevant information after moving. Here are some of the cursor movement functions that have been speech enabled. Note that this list only enumerates a few of these speech enabled commands; the purpose of emacspeak is to speech-enable all of emacs and provide you spoken feedback as you work. Thus, this list is here only as a representative example of the kind of speech-enabling extensions Emacspeak provides. `C-n' or `M-x next-line' or `down'" Moves the cursor to the next line and speaks it. `C-p' or `M-x previous-line' or `up'" Moves the cursor to the previous line and speaks it. `M-f' or `M-x forward-word' or" Moves the cursor to the next word and speaks it. Places point on the first character of the next work, rather than on the space preceding it (This is my personal preference). `M-b' or `M-x backward-word'" Moves the cursor to the previous word and speaks it. `M-C-b' or `M-x backward-sexp'" Moves the cursor to the previous sexp and speaks it. If the sexp spans more than a line, only the first line is spoken. `M-<' or `M-x beginning-of-buffer'" Speaks line moved to. `M->' or `M-x end-of-buffer'" Speaks line moved to. `M-m' or `M-x back-to-indentation'" Speaks entire current line. A useful way of hearing the current line. 5.2. Emacspeak Introduction - New Commands Emacspeak provides a number of commands for reading portions of the current buffer, getting status information, and modifying Emacspeak's state. All of the commands are documented in the subsequent sections. They can be classified into types: Emacspeak commands for listening to chunks of information. The names of these commands all start with the common prefix `emacspeak-'. All Emacspeak commands are bound to the keymap EMACSPEAK-KEYMAP and are accessed with the key `Control e'. Thus, the Emacspeak command "emacspeak-speak-line" is bound to `l' in keymap EMACSPEAK-KEYMAP and can be accessed with the keystroke `Control-e l'. Here are some of the commands for reading text: `C-e c' or `M-x emacspeak-speak-char'" Speak current character, using the phonetic alphabet. `C-e w' or `M-x emacspeak-speak-word'" Speak current word. `C-e l' or `M-x emacspeak-speak-line'" Speak current line. With prefix `C- u', speaks the rest of the line from point. With negative prefix `C-u -', speaks from start of line to point. Voicifies if voice-lock-mode is on. Indicates indentation with a tone if audio indentation is in use. Indicates position of point with an aural highlight if option emacspeak-show-point is turned on --see command `M-x emacspeak-show-point'. `C-e .' or `M-x emacspeak-speak-sentence'" Speak the current sentence. `C-e C-c' or `M-x emacspeak-speak-current-window'" Speak everything in the current window. `C-e =' or `M-x emacspeak-speak-current-column'" State the column where point is. The second category of commands provided by Emacspeak manipulate the state of the speech device. The names of these commands start with the common prefix `dtk-'. You can access these commands via the prefix `Control-e d'. Thus, the command "dtk-set-rate" is bound to `r' in keymap EMACSPEAK-DTK-SUBMAP and can be executed by pressing `Control e d r'. `C-e s' or `M-x dtk-stop'" Stop speech now. In addition, any command that causes speech output will discard anything in the speech buffer. `C-e d I' or `M-x dtk-toggle-stop-immediately-while-typing' Toggle state of variable dtk-stop-immediately-while-typing. As the name implies, if true then speech flushes immediately as you type. `C-e d i' or `M-x emacspeak-toggle-audio-indentation' Toggle state of Emacspeak audio indentation. Specifying the method of indentation as `tone' results in the DECtalk producing a tone whose length is a function of the line's indentation. Specifying `speak' results in the number of initial spaces being spoken. `C-e d k' or `M-x emacspeak-toggle-character-echo' Toggle state of Emacspeak character echo (that is, whether typed characters are echoed). `C-e d w' or `M-x emacspeak-toggle-word-echo' Toggle state of Emacspeak word echo (initially on). `C-e d l' or `M-x emacspeak-toggle-line-echo' Toggle state of Emacspeak line echo (that is, whether typed text is echoed after typing enter). `C-e d p' or `M-x dtk-set-punctuations' Set punctuation state. Possible values are `some', `all', or `none'. `C-e d q' or `M-x dtk-toggle-quiet' Toggle state of the speech device between being quiet and talkative. Useful if you want to continue using an emacs session that has emacspeak loaded but wish to make the speech shut up. `C-e d R' or `M-x dtk-reset-state' Restore sanity to the Dectalk. Typically used after the Dectalk has been power cycled. `C-e d SPC' or `M-x dtk-toggle-splitting-on-white-space' Toggle state of emacspeak that decides if we split text purely by clause boundaries, or also include whitespace. `C-e d r' or `M-x dtk-set-rate' Set speaking rate for the dectalk. `C-e d s' or `M-x dtk-toggle-split-caps' Toggle split caps mode. In split caps mode, a transition from lower case to upper case is treated like the beginning of a new word. This is useful when reading Hungarian notation in program source code. `C-e d v' or `M-x voice-lock-mode' Toggle Voice Lock mode (initially off). When Voice Lock mode is enabled, text is voiceified as you type it, as follows: o Comments are spoken in voice-lock-comment-personality; (That is a variable whose value should be a personality name.) o Strings are spoken in voice-lock-string-personality. o Documentation strings are spoken in voice-lock-doc-string- personality. o Function and variable names in their defining forms are spoken in voice-lock-function-name-personality. o Certain other expressions are spoken in other personalities according to the value of the variable voice-lock-keywords. `C-e d V' or `M-x emacspeak-dtk-speak-version' Use this to find out which version of the Dectalk firmware you have. 5.3. Emacspeak Introduction - Using the Help System When you press C-h to get the help index, the screen will appear, but Emacspeak will not speak the window. The only thing spoken is "Type one of the options listed or Space to scroll:". Here is the menu that Emacspeak is not speaking: -- begin quote You have typed C-h, the help character. Type a Help option: (Use SPC or DEL to scroll through this text. Type q to exit the Help command.) a command-apropos. Give a substring, and see a list of commands (functions interactively callable) that contain that substring. See also the apropos command. b describe-bindings. Display table of all key bindings. c describe-key-briefly. Type a command key sequence; it prints the function name that sequence runs. f describe-function. Type a function name and get documentation of it. C-f Info-goto-emacs-command-node. Type a function name; it takes you to the Info node for that command. F view-emacs-FAQ. Shows emacs frequently asked questions file. i info. The info documentation reader. k describe-key. Type a command key sequence; it displays the full documentation. C-k Info-goto-emacs-key-command-node. Type a command key sequence; it takes you to the Info node for the command bound to that key. l view-lossage. Shows last 100 characters you typed. m describe-mode. Print documentation of current major mode, which describes the commands peculiar to it. n view-emacs-news. Shows emacs news file. p finder-by-keyword. Find packages matching a given topic keyword. s describe-syntax. Display contents of syntax table, plus explanations t help-with-tutorial. Select the Emacs learn-by-doing tutorial. v describe-variable. Type name of a variable; it displays the variable's documentation and value. w where-is. Type command name; it prints which keystrokes invoke that command. C-c print Emacs copying permission (General Public License). C-d print Emacs ordering information. C-n print news of recent Emacs changes. C-p print information about the GNU project. C-w print information on absence of warranty for GNU Emacs. -- end quote Suppose you type "a", for command-apropos. The next spoken prompt is "Apropos command (regexp):" Now you type some word you think is part of an emacs command, like "visit". The help system will display the first section of the help, but will leave the cursor in the other window. The spoken text is "Type C-x 1 to remove help window. M-C-v to scroll the help." At this point, I think it's more helpful to move point to the other window with C-x o, then you can use regular navigation commands to speak the help text. You can delete the help window with C-x 0, which will also put point back where it was. The complete menu displayed by help-for-help is also visible if you do a describe function on help-for-help. In a future version of Emacspeak, Raman plans to add a message to that effect when the user presses C-h ? 6. Footnotes and References 6.1.

Emacs for DOS From the Emacs FAQ of November 11, 1996: --begin quote 93: Where can I get Emacs for my PC running MS-DOS? A pre-built binary distribution of Emacs 19.34 should be available by the beginning of November 1996 from the Simtel archives, the main site of which is at <ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/> If you prefer to compile Emacs for yourself, you will need a 386 (or better) processor, and are running MS-DOS 3.0 or later. According to Eli Zaretskii eliz@is.elta.co.il and Darrel Hankerson hankedr@dms.auburn.edu, you will need the following: Compiler: djgpp version 1.12 maint 1 or later. Djgpp 2.0 or later is recommended, since 1.x is being phased out. Djgpp 2 supports long filenames under Windows 95. You can get the latest release of djgpp by retrieving all of the files in <ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp> Gunzip and tar: The easiest way is to use "djtar" which comes with djgpp v2.x, because it can open gzip'ed tarfiles (i.e., those ending with ".tar.gz") in one step. Djtar comes in "djdev201.zip", from the URL mentioned above. Utilities: make, mv, sed, rm. All of these utilities are available at <ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu> 16-bit utilities can be found in GNUish: <ftp://ftp.simtel.net/pub/simtelnet/gnu/gnuish> The file INSTALL in the top-level directory of the Emacs source contains some additional information regarding Emacs under MS-DOS. In addition, the file etc/MSDOS contains some information on the differences between the Unix and MS-DOS versions of Emacs. For the most comprehensive information on running GNU Emacs on a PC, see the file prepared by Michael Ernst mernst@theory.lcs.mit.edu at <ftp://theory.lcs.mit.edu/pub/emacs/pc-emacs.gz> For a list of other MS-DOS implementations of Emacs (and Emacs look- alikes), consult the list of "Emacs implementations and literature," available at <ftp://rtfm.mit.edu/pub/usenet/comp.emacs/> Note that while many of these programs look similar to Emacs, they often lack certain features, such as the Emacs Lisp extension language. --end quote 6.11.

Emacspeak with Earlier Slackware Releases If you want to install Slackware 3.0 or earlier, you will need to prepare a full null modem cable, including modem control signals. For two DB25 (25 pin) connectors, the required connections are: o 1 (Frame Ground) - 1 (Frame Ground) o 2 (Receive Data) - 3 (Transmit Data) o 3 (Transmit Data) - 2 (Receive Data) o 4 (Request To Send) - 5 (Clear To Send) o 5 (Clear To Send) - 4 (Request To Send) o 6 (Data Set Ready) - 20 (Data Terminal Ready) o 7 (Signal Ground) - 7 (Signal Ground) o 8 (Carrier Detect) - 20 (Data Terminal Ready) o 20 (Data Terminal Ready) - 6 (Data Set Ready) o 20 (Data Terminal Ready) - 8 (Carrier Detect) For two DB9 connectors, the connections are: o 1 (Carrier Detect) - 4 (Data Terminal Ready) o 2 (Receive Data) - 3 (Transmit Data) o 3 (Transmit Data) - 2 (Receive Data) o 4 (Data Terminal Ready) - 6 (Data Set Ready) o 4 (Data Terminal Ready) - 1 (Carrier Detect) o 5 (Signal Ground) - 5 (Signal Ground) o 6 (Data Set Ready) - 4 (Data Terminal Ready) o 7 (Request To Send) - 8 (Clear To Send) o 8 (Clear To Send) - 7 (Request To Send) o 9 (Ring Indicator) not connected For a DB9 (listed first) to a DB25 (second), the connections are: o 1 (Carrier Detect) - 20 (Data Terminal Ready) o 2 (Receive Data) - 2 (Transmit Data) o 3 (Transmit Data) - 3 (Receive Data) o 4 (Data Terminal Ready) - 6 (Data Set Ready) o 4 (Data Terminal Ready) - 8 (Carrier Detect) o 5 (Signal Ground) - 7 (Signal Ground) o 6 (Data Set Ready) - 20(Data Terminal Ready) o 7 (Request To Send) - 5 (Clear To Send) o 8 (Clear To Send) - 4 (Request To Send) o 9 (Ring Indicator) not connected 7. Frequently Asked Questions (FAQ) 7.1. Why does it say "space" after each character? Your DECtalk Express has old firmware. Use the Emacspeak command `C-e d V' to find out your version. You should be running a version no older than 4.2bw from March 1995. If you have an earlier version, you can find an updated version at <http://www.ultranet.com/~rongemma/tips_upd.htm>, a WWW site maintained by Ron Jemma of the Dectalk Group at DEC. Alternatively, you can send email to Anne Nelson at DECnelson@dectlk.enet.dec.com. The most recent version at this writing is 4.3 release AA X01 May 20 1996. 7.2. tones that last for several words or more, if this happens in a buffer it will often repeat within the same buffer. On occasion when reading the dectalk will produce high pitch The problem is due to remaining bugs in the Dectalk firmware. When emacspeak produces tones, especially when split caps is on, the dtk sometime goes into squealing mode. If you notice this happening in particular text documents, just turn off split caps mode locally with `C-e d s'. 7.3. autorevert in search path" which is spoken (or at least queued for speech) when emacspeak 7.0 starts? What is the significance of the message "No library It's completely insignificant. autorevert is a new minor mode provided by emacs 20 and emacspeak looks for it and if found speech-enables it. 8.
