- Pcomm
- A Unix Telecommunication Program
-
- Things to do first:
-
- 1) Figure out what files you need to extract. There is a shell
- archive called "Unixpc.shar" that contains additional (and
- replacement) files for users of the AT&T Unix PC 7300/3b1.
-
- 2) Create a default directory where the Pcomm support files will
- go. A good location might be /usr/local/lib/pcomm.
-
- 3) Copy the sample support files Pcomm.dial_dir, Pcomm.modem,
- and Pcomm.param to the default directory and rename them to
- change the uppercase "P" to a lower case "p". The files should
- *not* have write permission to all.
-
- 4) Copy (and rename as appropriate) the Pcomm.1 nroff manual to
- the proper /usr/man directory.
-
- 5) Print the Doc file by piping the output of the Unix "pr"
- command with the title separated by lots of white space (to help
- center it), for example:
-
- pr -h " Pcomm Reference Manual " Doc | lp
-
- How to configure Pcomm:
-
- 1) Edit the "config.h" file to suit your system's needs and your
- personal taste. Sites running HoneyDanBer (HDB) UUCP should pay
- particular attention to the LOCK_DIR, ASCII_PID, and SETUGID
- definitions. The definitions in config.h are:
-
- UNIXPC If defined, use the dial(3) routines specific
- to the AT&T Unix PC 7300/3b1. Useful only if
- the On Board Modem (OBM) is to be used.
-
- OLDCURSES If defined, use the older version of curses(3).
- (uses termcap in lieu of terminfo). Some
- versions of the AT&T Unix PC 7300/3b1 may
- require this.
-
- SHAREDMEM If defined, keeps the virtual screen area in
- shared memory rather than in a file. Some
- performance gains are realized if shared memory
- is used.
-
- NOPROMOTE If defined, do not promote missing video
- attributes to standout. Normally, curses(3)
- attempts to compensate for missing attributes.
-
- SETUGID If defined, extra precautions are taken before
- opening files or doing a shell escape to restore
- the real UID/GID. Useful if Pcomm is installed
- as a set-user-id or get-group-id program. HDB
- programs often are set-user-id to uucp.
-
- LOG_CALLS If defined, Pcomm will keep an administrative log
- of all calls. The log contains the name of the
- person making the call, the phone number, and a
- date/time stamp. Useful for verifying long
- distance phone bills.
-
- LOGFILE The path to the log file (if LOG_CALLS is
- defined). It should have write permission to
- all or be writeable under set-user/group-id
- conditions.
-
- LIMIT_LD If defined, Pcomm will limit long distance
- (toll) calls to a privileged group. The file
- "admin.c" may require tweeking to detect what is
- a long distance number.
-
- GROUP_NAME The name of the group that is allowed to make
- long distance calls (if LIMIT_LD is defined).
-
- LPR The path to the line printer program (this is
- not the name of the device).
-
- LPRINT The path to the "pretty" line printer program.
- Typically a program that performs a "pr | lp"
- function. If none exist, use the same as LPR.
-
- DEFAULT_DIR The path to the directory that contains the
- default Pcomm support files.
-
- LOCK_DIR The path to the directory where the UUCP lock
- files are found. On HDB systems this would
- typically be /usr/spool/locks.
-
- ASCII_PID If defined, the lock files will contain an ASCII
- encoded process id (PID). On HDB systems this
- is the default.
-
- KEEP_PORT If defined, the port will be kept open between
- dialing attempts to save time. Some systems
- may require the modem to be closed and reopened
- every time.
-
- XMC_BROKE Does the status line scroll up when using "magic
- cookie" terminals? Some Pyramid and AT&T
- systems may require this to be defined. Find a
- magic cookie terminal (a Wyse 50 for example),
- and see what happens.
-
- WGETCH_BROKE Does the alarm() system call work correctly with
- the wgetch() function? Some Masscomp systems
- will require this to be defined. Symptom: the
- initial screen doesn't go away by itself after 5
- seconds.
-
- 2) Edit the Makefile. There are provisions in the Makefile to
- include getcwd() and getopt() routines if they are missing from
- your system. You may want to customize the CFLAGS, LDFLAGS, and
- BIN assignments to suit your needs.
-
- 3) Compile pcomm and pcomm_input. Type "make". The Makefile
- will attempt to install "pcomm" and "pcomm_input" into the BIN
- directory given in the Makefile. However, those sites running
- HDB UUCP software may require you to change the mode of "pcomm"
- to be set-user-id to uucp. DO NOT CHANGE THE SET-UID/GID BITS
- ON THE "pcomm_input" PROGRAM.
-
- 4) Update the sample modem/TTY database. I know I'm asking the
- impossible, but... Read section 3 and the Appendices of the Doc
- file first, then run Pcomm to update the modem/TTY database by
- using the TTY Setup and the Modem Setup menues. You will need
- to know:
-
- o The types and number of modems available for dial out
- o The TTY ports attached to the modems
- o The range of baud rates at which the modems operate
- o How to initialize the modems to suit Pcomm's needs
- o How to make the modems dial
-
- During this step, you will need write permission on the support
- files in the default directory. RESIST THE TEMPTATION TO EDIT
- THE SUPPORT FILES DIRECTLY.
-
- Portability considerations:
-
- 1) This program was written with AT&T System V in mind. It
- makes use of System V specific routines such as shared memory
- and the ioctl() calls of termio(7). There is currently no
- port to Berkeley or v7 Unix.
-
- 2) Pcomm makes use of the bold, blinking and standout video
- attributes. My concept of "standout" and "reverse" might be
- different than yours (I like "standout" to be a brighter version
- of "reverse"). Check your terminfo database...
-
- 3) The "port.c" file has a place where you can include your own
- routine to toggle the getty process on a port (if required).
-
- 4) If you compile Pcomm with LOG_CALLS defined, you'll have to
- look at the code in "admin.c" to see if the long distance
- detection routine is correct for your site.
-
- 5) Compilers that adhere to the draft ANSI C Standard will bark
- at the declartions of signal(), perror(), malloc(), fread(), and
- fwrite().
