[3] Macintosh File-transfers
============================

[3.1] What programs support Kermit, FTP (client), and/or X,Y,Z-MODEM
--------------------------------------------------------------------
        and where can I get them?

        The following is a fairly complete list of the popular free, shareware,

        The archive sites described in the Appendix are the best place
        to look for free or shareware file-transfer programs. Other
        commercial but non-shareware ("payware") products must be
        purchased from a dealer or the company directly.

        Table 3.1.1 summarizes file transfer capabilities of various
        Macintosh telecommunications programs.

                                Table 3.1.3

        Note: SITcomm is fully AppleScript-able (all features can be
        controlled through AppleScript). The Frontier Runtime portion
        of the Frontier scripting system is also bundled with SITcomm.

        ! Although PacerTerm does not support arrays per se, it
          does implement HyperTalk's chunk expressions that allow
          any variable to be referred to as a collection of
          characters, items, words, or lines.

        The February, 1993 issue of "MacUser" reviews White Knight,
        MicroPhone II, Smartcom II (for the Macintosh), ZTerm, and
        MacIntercomm. The review is also useful for those new to
        telecommunications in general.

        Peter Newton's DialScript 1.7, archived at rascal.ics.utexas.edu,
        is a telecommunications scripting utility useful for automating
        complicated logins and then automatically launching applications
        or startup documents. It's free and the source is available.


[3.2] What is the latest version of ZTerm?
------------------------------------------

        ZTerm is currently at revision level 0.9 (4/93). Other released
        versions were 0.7, 0.75 and 0.8, and 0.85.

        Two "fake" versions of ZTerm have circulated. Recently (4/93),
        a hacked version called "ZTerm 0.93 XK", based on 0.9, was
        distributed.

        An older also fake version labelled "ZTerm 1.0" has also been
        seen. Neither versions were released by the author, Dave Alverson.

        For the latest scoop on ZTerm, as well as advice on features, bugs,
        bug fixes, and more, see Leslie Jones' ZTerm FAQ which is posted
        to comp.sys.mac.comm, comp.sys.mac.apps, news.answers, and the
        InfoMac and UMich archives.


[3.3] What is the Communications Toolbox (CTB)?
-----------------------------------------------

        The Communications Toolbox is a Macintosh operating system
        interface that provides a standard interface for programmers
        writing communications programs. Rather than make calls to
        control the modem serial port, for example, a programmer can
        call an equivalent CTB routine. This allows the operating system
        to manage the serial port(s) just like any other limited
        resource. In addition, specific "tools" that interface with
        modems, provide terminal emulation, or handle file transferring
        can be implemented as external add-on features to CTB-aware
        programs.

        The CTB requires System 6.0.4 or later. The CTB is built into
        System 7. Tools can be added by placing them in the Extensions
        folder; rebooting is not necessary. Under System 6.0.X, CTB
        tools belong in the Communications folder.


[3.4] Are there any shareware or freeware tools that support Kermit,
--------------------------------------------------------------------
        and/or X,Y,Z-MODEM?

        Termy 1.0, freeware from Ice Engineering, is the only CTB-aware
        application that can be obtained via anonymous FTP. Termy has
        no built-in support for any connection methods, file transfer
        protocols, or terminal emulation, so you will need to obtain
        Communication Toolbox tools for each of these.

        Tim Endres has written and released TGE TCP Tool, a Connection
        Tool for the Communications Toolbox. It provides TELNET and
        transparent TCP connections. The tool is free for personal use.

        Several modem Connection tools are available from the various
        FTP sites. These include the Apple Modem Tool 1.11, the Hayes
        Modem Tool 1.02, the CCL Modem Tool 1.0, and the Zoom Modem
        Tool 1.11. After recently releasing his CTB File Transfer tool,
        Kermit Tool GH (which supports MacBinary, RLE compression,
        and other features), Glenn Howes has gone on to release a YMODEM
        tool.

        The Basic Connection Tools Disk is available from ftp.apple.com
        as /dts/mac/sys.soft/netcomm/basic-conn-set-1-1-1-image.hqx .
        You will need DiskCopy or MountImage to decode the image file.
        This disk includes VT102 and TTY terminal tools, XMODEM and Text
        File Transfer tools, and Modem, Serial, and Appletalk
        Connection tools (10/92).

        Advanced Software Concepts has demonstration versions of
        several CTB tools at InfoMac sites in the demo directory.
        Demo versions of a TCP/IP Connection tool, an FTP File Transfer
        tool, as well as VT420, IBM3270, and IBM5250 Terminal tools
        are being distributed (10/92).

        Stalker Software has a demonstration version of its VideoTex
        terminal tool at InfoMac sites. Stalker has also released a
        free CEPT Modem Tool, which is equivalent to the CCL Modem Tool
        but also supports the CEPT-1 low-level protocol used by European
        VideoTex systems.

        New free and shareware CTB tools inevitably get posted to Info-
        Mac where they appear in the info-mac/comm directory and also
        to mac.archive.umich.edu in mac/system.extensions/commtoolbox.
        If you give the command "ls *tools*" in these directories
        through an anonymous FTP connection, you can get a list of
        all the free and shareware CTB tools currently available.

        There are also a number of available *payware* tools:

        o MicroPhone Pro includes a Telnet tool (along with some FAX
        support software). MicroPhone II does not include the Telnet
        tool, unfortunately.

        o PacerTerm ships with a broad collection of tools, including:
        XMODEM, ZMODEM, Kermit, and FTP file transfer tools; Telnet,
        LAT, ADSP, and serial connection tools; and TTY, VT102, and
        VT320 terminal tools.

        o Seaquest Software has released XMODEM, YMODEM, and Kermit file
        transfer tools. It also has been said to be developing a ZMODEM
        tool for well over a year now (8/93).

        o SITcomm ships with a full set of CTB tools; included are XMODEM,
        YMODEM, ZMODEM, and Kermit file transfer tools, as well as TTY and
        VT102 connection tools, and Apple Modem Tool v1.5.

        o Versaterm and Versaterm Pro include FTP client and server file
        transfer tools and Telnet, LAT, SL/IP, and ADSP connection
        tools.

        o 5PM ships with a Telnet Tool and the Apple Basic Connectivity
        Set (XMODEM, ADSP, serial, modem, TTY, VT102, VT320). Other tools
        are available from Advanced Software Concepts : FTP, VT420,
        IBM3270 and IBM5250.


[3.5] How can I transfer Macintosh files to/from my Macintosh and other
-----------------------------------------------------------------------
        non-Macintosh computers (eg: mainframes, UNIX boxes, PCs)?

        If your telecommunication program supports MacBinary (they
        almost all do), turn MacBinary on. This usually involves
        selecting a menu option or clicking a radio button in a
        'preferences' type dialog box. Then, transfer your file
        normally. Your Macintosh file will be sent as a MacBinary file
        that can be treated as an ordinary binary file.

        If your telecommunication program does not support MacBinary,
        get a copy of the MacBinary program and use it to make a
        MacBinary version of your Macintosh file. Then send this
        MacBinary file. Meanwhile, look around at the various shareware
        and commercial telecommunications programs that do support
        Macbinary. See [3.1].

        Note: Not all files need to be transferred as MacBinary files.
        In particular, most text and non-Macintosh specific binary files
        (like GIF/JPEG images) do not. See [2.2] for more information.

        To actually "download" a file (eg: transfer it from a remote
        host computer to your Macintosh), you must first instruct the
        remote computer to send the file by issuing a command. For
        example, to download a file from a Unix machine using XMODEM,
        you would first have to give a command similar to:

                % sx filename

        where 'sx' is the local Unix program to send a file using XMODEM
        and 'filename' is the name of the file you wish to send. Then,
        locally, you must start the file transfer by typically choosing
        a menu option in your terminal program. The process is similar
        for Kermit transfers. Terminal programs that support ZMODEM
        should recognize the start of a ZMODEM download automatically.

        Note: Not all systems are alike. The command to start XMODEM
        may not necessarily be 'sx'; another possibility is 'xmodem'.
        Ask your local system administrator if you cannot find the
        right program; most sites support something. Also, see the
        listing below.

        To upload, first issue the appropriate receive command on the
        remote host computer; then, select the local send option in your
        terminal program. Good ZMODEM packages can start the remote file
        transfer automatically.

        If you experience multiple CRC errors when downloading with
        ZMODEM, especially after backgrounding the download, try sending
        your file using a fixed window size, eg: 'sz -w 1024 filename'.
        If errors persist, also try escaping control characters,
        eg: 'sz -ew 1024 filename'. Depending on your setup, you may
        be able to use a larger window size (eg: use 4096 or 2048
        instead of 1024) which can slightly reduce transfer time.

        Typical Unix programs that support transfering files via a
        serial (modem) link:

        Kermit          XMODEM          YMODEM          ZMODEM
        -------         ------          ------          ------
        kermit          sx              sb              sz
        ckermit         xmodem

        If you are trying to transfer a lot of information between
        a Macintosh and an MS-DOS PC, and your Macintosh has an FDHD
        disk drive (also known as a SuperDrive), using Apple File
        Exchange, or any of the various shareware and payware programs
        that allow you to access (or even mount) MS-DOS formatted 3.5"
        HD diskettes, can greatly speed up the transfering process.
        Apple File Exchange even provides for automatic translation
        of certain types of files. If you are transfering a lot of
        information between a Macintosh and a Unix system, you can
        use the (free) Macintosh program suntar to read 1.44 MB Unix
        tar floppies.

        Note: On most Sun Microsystems' floppy drives, the appropriate
        formatting command is "fdformat -ev /dev/rfd0c". This will
        verify and eject the disk after formatting. Then use tar to
        copy files to the device /dev/rfd0c.


[3.6] What's the best compression program to use when uploading files
---------------------------------------------------------------------
        to an archive or BBS? Are there any other guidelines I should
        follow?

        Best Compression: (Revised 3/93)
        ---- -----------

        The shareware program StuffIt Lite ($25) (and its commericial
        sibling, StuffIt Deluxe) are generally regarded as providing
        the best compression performance of the many Macintosh
        compression utilities. Both programs also sport a fancy
        user-interface. Registered users of StuffIt Lite can upgrade
        to StuffIt Deluxe for $45, which includes many other compression
        tools that are not directly applicable to telecommunications.

        The shareware program Compact Pro ($25) provides similar compression
        performance to StuffIt Lite and also has a loyal set of users.

        Individual preferences differ, so the editor suggests you try
        using both programs (StuffIt Lite and Compact Pro are available
        for FTP at the various archives sites) and choose the one you
        like best. Note that StuffIt 1.5.1 and Stuffit Classic are
        *not* the same as, nor as good as, StuffIt Lite 3.0.

        Posting Macintosh Programs: (Revised 4/93)
        ------- --------- --------

        You should use either StuffIt Lite, StuffIt Deluxe, or Compact
        Pro to compress Macintosh files you send to anonymous FTP sites
        and BBS's. Do not post PackIt, Disk Doubler, SuperDisk, Zip,
        or any other type of archive (including self-extracting
        archives -- see below). Stuffit Lite 3.0 and Compact Pro
        have evolved as the standard archive formats for posting
        Macintosh files for good reasons.

        Regardless of which archiver you use, PLEASE DO NOT MAKE AN
        AN ARCHIVE YOU ARE POSTING SELF-EXTRACTING! The extra code
        added to the file to make it self-extracting is NOT insignificant
        in size. The convenience of self-extracting archives is not worth
        the space they waste at anonymous-FTP sites and BBS's (where
        literally thousands of compressed files are stored). Self-
        extracting archives are useful in other contexts, but should be
        discouraged as a medium for posting to archives. Also, don't
        rely on the archive maintainer having the time to extract your
        self-extracting post and re-archiving it; these volunteers are
        simply too busy to take on this additional burden.

        Before you create your archive, set the Finder label of all
        files you plan to include in the archive to 'None'.

        Avoid using strange punctuation marks in filenames that you
        will distribute. Characters such as exclamation points, spaces,
        dollar signs, etc, are legal characters in Macintosh filenames
        but can be difficult to work with on non-Macintosh systems
        (where most Macintosh archives are stored). Since BinHex and
        MacBinary store your original Macintosh filename, removing
        strange characters from a BinHex'd or MacBinary'd file before
        distributing will not affect the original filename. As an
        example, MyFile-215.sit is a perfectly acceptable filename.

        After you have created the archive and named it appropriately,
        BinHex encode it (see [2.3]). Edit the resulting text file
        and include a short description of the archive you want to
        distribute, including any system requirements and problems.
        If you include a signature, limit it to a single line.

        Finally, upload the text file (if necessary) and e-mail it
        to [e-mail]. Your subject line should
        specify a suggested name and location for your submission,
        eg:

              To: [e-mail]
              Subject: app/myfile-215.sit.hqx

        Mailing your archive to macgifts automatically submits it
        to the InfoMac archives, mac.archive.umich.edu, and the
        Usenet group comp.binaries.mac.

        Thanks for complying with these guidelines.


[3.7] How can I use the programs that are posted to comp.binaries.mac?
----------------------------------------------------------------------

        The files posted to comp.binaries.mac are in BinHex 4.0 format.
        Long files are split into several postings that must be
        concatenated IN THE PROPER ORDER (and usually with headers
        and signatures removed) before converting.

        First, read the man page or other documentation for your
        newsreader. A little time spent here can save you a lot of time
        doing repetitive tedious work later. Find out how to save an
        article to a file.

        Next, save all the posted articles for a given program posted to
        comp.binaries.mac to a single file. Don't combine postings that
        are for different programs, but do save multi-part postings to
        the same file, in increasing order of part number. For example,
        if you are using the UNIX newsreaders 'rn', 'trn', or something
        similar:

        *****  15 unread articles in comp.binaries.mac--read now? [=ynq]
         2761 Great Icon Editor (part 1 of 2)
         2762 Great Icon Editor (part 2 of 2)
         2764 Hypercard Resource Tools
         2765 Idea 1.2 (part 01 of 11)
         2766 Idea 1.2 (part 02 of 11)
         2767 Idea 1.2 (part 03 of 11)
         2768 Idea 1.2 (part 04 of 11)
         2769 Idea 1.2 (part 05 of 11)
         2770 Idea 1.2 (part 06 of 11)
         2771 Idea 1.2 (part 07 of 11)
         2772 Idea 1.2 (part 08 of 11)
         2773 Idea 1.2 (part 09 of 11)
         2774 Idea 1.2 (part 10 of 11)
         2775 Idea 1.2 (part 11 of 11)
        What next? [npq] 2761 s iconeditor.hqx
        2761    Saved to mailbox /u/joe/News/iconeditor.hqx
        What next? [npq] 2762 s iconeditor.hqx
        2762    Saved to mailbox /u/joe/News/iconeditor.hqx

        At this point, download the file "iconeditor.hqx" (it will be
        automatically placed in your "News" directory) to your Macintosh
        and use a program like StuffIt Expander, DeHqx, HQXer, or Compact
        Pro to convert the .hqx file to a Macintosh file.

        Warning:  The original BinHex utility, BinHex 4.0, has a bug
        that causes it to crash on large or corrupted .hqx files. It
        also requires you to strip mail-headers off of .hqx files before
        decoding.

        The Macintosh file you create may in fact be an archive that you
        then need to unarchive with the appropriate program. See the
        list of file suffixes to determine which program(s) to use.

        Note: You can streamline the process by:

        --> using the Unix program 'mcvert' or 'hexbin' (see [6.5]) to
            convert the .hqx file to a MacBinary file on your Unix host.
            Since the .hqx file is usually 30% to 40% larger than the
            MacBinary file, this saves download time. These utilities
            are also smart enough to handle stripping headers and
            signatures, although you must still save the postings in the
            proper order.

        --> using one of the many utilities that exist to reorder
            postings automatically before you convert them from
            BinHex

        --> learning enough about your newsreader program to save more
            than one article at once in a particular order

        --> checking out the programs: StuffIt Expander, DeHqx and HQXer

================================================================================
[4] Introduction to AppleTalk (and Remote AppleTalk)
====================================================

[4.1] What kind of hardware do I need to set up an LocalTalk network?
---------------------------------------------------------------------

        Be sure you have read section [5] and understand the difference
        between LocalTalk and PhoneNet. Setting up an AppleTalk network
        based on either LocalTalk or PhoneNet requires purchasing a box
        that connects to your Macintosh's serial (printer) port with the
        appropriate mini DIN-8 or DB-9 connector and provides, in the
        case of LocalTalk, two mini DIN-8 connectors for Apple's
        (expensive) multiwire AppleTalk cables, or, in the case of the
        less expensive PhoneNet, two standard RJ11 (modular telephone)
        jacks. Both boxes look similar to Figure 4.1.1.

                        +-----------------+
        to/from <------>|                 |
        rest of         |                 |<-------->  to Macintosh or
        network <------>|                 |                 printer
                        +-----------------+

                                Figure 4.1.1

        Computers and printers should be connected serially; that is,
        chain the devices in any convenient order, with either
        a single AppleTalk cable (LocalTalk network) or telephone
        cable (PhoneNet network) connecting neighboring machines.
        Do *not* connect the ends of a LocalTalk or PhoneNet
        network --- this is not a ring (eg: TokenRing) network.

        It should be noted that Apple is "strongly encouraging"
        new AppleTalk networks to be Ethernet-based.


[4.2] How can I change the Chooser "user" and name of my Macintosh?
-------------------------------------------------------------------
      Also: Why can I no longer change the name of my hard-disk?

        To change the owner and name of your Macintosh under System 7,
        select "Controls Panels" from the Apple Menu and double-click
        on the "Sharing Setup" Control Panel.

        The Chooser "user" is the "Owner name:". Change it like any
        standard edit field.

        The name of your Macintosh is the "Macintosh name:".

        Also on this Control Panel is a button to turn File Sharing
        on and off. When File Sharing is on, you cannot change the
        name of shared disks. If you are trying to change the name
        of your hard disk but cannot get the name to turn into an
        edit field, File Sharing is probably on. Use the Sharing
        Setup Control Panel to turn File Sharing off, change your
        hard disk name, and then turn File Sharing back on (unless
        you have no need for it).


[4.3] What is AppleTalk Remote Access ?
---------------------------------------

        Apple's AppleTalk Remote Access is a software package that
        allows you to dial-in to an AppleTalk network (or to create
        an AppleTalk network between two Macintoshes via dial-up
        modems) from a remote Macintosh. Remote Access requires
        at minimum:

            o   a Macintosh (possibly connected to an AppleTalk
                network) designated as the host with a dedicated
                high speed modem

            o   one or more remote Macintoshes with modems

            o   a phone line connecting the host Macintosh with
                the remote Macintosh

            o   copies of the Remote Access software running on the
                designated host as well as on all remote machines

        Once configured, connecting the remote machine to the AppleTalk
        network is as simple as clicking a button. Modem control is
        handled automatically (assuming one of the many included modem
        scripts works with your modem; see [4.4]). Passwords and call-
        back facilities are provided.

        Once connected, the remote machine can use the AppleTalk
        network normally. One can print remotely, send messages,
        access remote filesystems, monitor network traffic, etc.

        Throughput, even when using 9600 baud modems, will be
        significantly lower than through a LocalTalk or PhoneNet
        connection; however, except for program launching and file
        copies, the added delay is small.

        You CAN use slower 2400 baud modems, but you will probably not
        enjoy the experience.


        The University of Melbourne has developed a useful but not
        well known package known as ARNS, or A Remote Network Server.
        ARNS allows remote clients to use network services such as
        printing and file sharing. The server runs on a UNIX host;
        clients connect through an IP interface (e.g. MacTCP, CAP).
        With ARNS, it is possible to use a dial-up SL/IP account to
        tunnel into an existing UNIX based AppleTalk network. For more
        information, anonymously FTP to munnari.oz.au, directory mac.


[4.4] Where can I get a Remote Access script for my modem?
----------------------------------------------------------

        If none of the (many) included modem scripts work with your
        modem, try:

            o   searching the InfoMac archives for a script for your
                modem; several scripts have been posted recently

            o   making a copy of the script that works best with
                your modem (the scripts are in the Extensions Folder
                which is in the Systems Folder), opening it up with
                a text editor, and experimenting; this assumes you
                have a copy of your modem's manual and know the
                basics about the Hayes command set. If you are
                succesful, post your script so others can benefit!
