Title: GPRS modem and /usr/sbin/chat
Post by: nakor on August 18, 2004, 11:28:03 pm

Hi,

I think I've encountered a bug in the /usr/sbin/chat program.
Whenever it's executed during my connectgprs script, the shell that launches it closes.

To test this I've actually opened an xterm/aterm and typed:

exec /usr/sbin/chat

the end result has been the xterm/aterm closing.

I closed out of mb and attempted the same command from the shell.  This time finding myself
at a log in prompt.

I've been using this scripts on the previous version of pdaXrom pretty much since it's first release.
If it would be helpful, I can post the scripts tomorrow when I can cut/paste them over(they have very funky and specific tab requirements).

the modem I'm attempting to connect with is an AudioVOX RTM-8000 and I'm using the Kathrin RC2 distro an a C860.

I'd have to say that other then this issue, i've had no problems with Kathrin so far.  Excellent work!!

From the bash(1) man page:

Code: [Select]

      exec [-cl] [-a name] [command [arguments]]
              If  command is specified, it replaces the shell.  No new process
              is created.  The arguments become the arguments to command.   If
              the -l option is supplied, the shell places a dash at the begin-
              ning of the zeroth arg passed to command.  This is what login(1)
              does.  The -c option causes command to be executed with an empty
              environment.  If -a is supplied, the shell passes  name  as  the
              zeroth  argument  to the executed command.  If command cannot be
              executed for some reason, a non-interactive shell exits,  unless
              the  shell  option execfail is enabled, in which case it returns
              failure.  An interactive shell returns failure if the file  can-
              not  be executed.  If command is not specified, any redirections
              take effect in the current shell, and the return  status  is  0.
              If there is a redirection error, the return status is 1.
Particularly, note "command ...  replaces the shell".

ah, well, there's that and to complete my err.  the problem ended up being that I forgot to set the /etc/pcmcia/serial.opt files SERIAL_OPTS value to "uart 16550A"  been a while .

Thanks though.
