- Questions and Answers
- for the most common Pcomm problems.
-
- 1) The "elpase time" doesn't increment during a dialing attempt.
-
- This is a symptom of a bug in the wgetch() routine in the curses
- library. The work-around is to set WGETCH_BROKE in the config.h
- file and recompile.
-
- 2) I can't get Pcomm to dial, it just sits there.
-
- This typically is due to the wrong device name for the tty port.
- Some systems have more than one name (different minor device
- numbers) for the same tty port. UUCP may use the device name
- that has "modem control" enabled; if so, that is the one Pcomm
- needs to use.
-
- 3) How do you make Sun's dial in and out on the same port?
-
- Sun Sparc boxes don't come configured for doing dialin and dialout
- on the same serial port. However, there is a blurb in the printed
- manual that tells you what to do...
-
- Make a new device (cua0 for ttya, and/or cua1 for ttyb)
- mknod /dev/cua0 c 12 128
- mknod /dev/cua1 c 12 129
-
- Edit /etc/ttytab. Change the ttya (or ttyb) line to look like
- the following. Look in the /etc/gettytab file for the choices
- for the second field (std.38400, in this example).
- ttya "/usr/etc/getty std.38400" dialup on remote secure
- ttyb "/usr/etc/getty std.38400" dialup on remote secure
-
- Edit /etc/uucp/Devices. Add a line for each speed your modem
- supports. The dialer field (hayes, in this example) must match
- whatever you've got in /etc/uucp/Dialers.
- ACU cua0 cua0 1200 hayes
- ACU cua0 cua0 2400 hayes
- ACU cua0 cua0 9600 hayes
- ACU cua0 cua0 19200 hayes
- ACU cua0 cua0 38400 hayes
-
- 4) I get a measage that tells me I can't create the lockfile (or can't
- open the tty port).
-
- Pcomm is typically configured to be set-user-id to uucp. To do
- this, you type (as root):
- chown uucp pcomm
- chmod 4755 pcomm
-
- 5) As soon as I am connected, the modem lights go crazy.
-
- This is probably caused by an improper UUCP lock file. Pcomm
- understands several variations of UUCP lock files, but must
- match the one used by your UUCP. Read the Readme file and check
- the LOCK_DIR, ASCII_PID, SVR4_LOCKS, and XENIX_LOCKS in the
- config.h file.
-
- 6) I've got a V.32bis modem but without locked DTE speeds, how do I
- setup Pcomm for this?
-
- Change the tty database so that the "locked speed" entry is set
- to zero. Then change the "auto-baud detect" flag in the modem
- database to 'N'.
-
- In this configuration, the modem will always use the DTE speed
- as specified in the dialing directory. The status line will
- show this speed, regardless of the actual connected baud rate.
-
- 7) Some of the Pcomm screens appear messed up.
-
- Yes, that's unfortunately quite common... It's a bug in either
- the curses library or the termcap/terminfo database. I've
- included a terminfo entry for AT386 in the Readme file, that
- seemed to fix the problem for my 386 box.
-
- 8) Where do I get xmodem/ymodem/zmodem stand-alone programs for Unix?
-
- I use Xmodem v3.8 by Steve Grandi, and an older version of rzsz
- by Omen Technologies. Both of these should be available at a
- neighboring archive site.
-
- 9) I can't get the external zmodem programs "rz" and "sz" to work from
- inside Pcomm.
-
- The authors of rz and sz have deliberately broken the program so
- that it will not work from inside another program. See if you
- can find an older version.
