Can anyone help get me started

[Cyril Spiro]

I am a newbie to mgetty.



Trying to get it running. Will use PERL scripts to send and receive faxes.



Hardware:

Internal modem came with Dell server (only 2 years old) and is recognized by
Linux O/S.

Minicom config menu shows modem at /dev/ttyS1

mgetty & mgetty-faxsend both loaded on RedHat Linux 9 via up2date, loaded
version: 1.1.31-Jul24



Here is the inittab file:

networking)

Can you make calls using minicom? Try something like ATDT123 and see
whether the modem actually responds to that command. If not, you have a
driver problem.

You will want to add a line to start faxrunqd as well in the inittab,
to automatically send out queued faxes. My modem is at /dev/ttyS0, and
I have in the inittab these lines. Modem answers after four rings,
speed 38400.

FaxS:2345:respawn:/usr/sbin/faxrunqd
FaxR:2345:respawn:/sbin/mgetty -s 38400 -n 4 ttyS0

I'd guess wrong port setting or driver problem. Try inittab without the
/dev/, like in my example above.

Check you sendfax.config: wrong modem port setting.
Note that sendfax and mgetty have separate port settings; you could use
them on different modems if you have more than one. So set them both!

Minicom config doesn't really say anything about "is the modem really there".

What does the kernel messages say about it (how do you know that the
modem is "recognized by Linux O/S")?

/dev/ is optional, and mgetty will handle with and without just fine.

I'd say "there is nothing on /dev/ttyS1, or if it is, it's not handling
the necessary ioctl() calls very well".

Hi,

Gert, you were right. What I mistook for O/S recognition of the modem was
that the modem was recognized by the Dell server and not the O/S.

So, I installed the appropriate modem driver for the Linux RedHat Kernel and
now the modem indicates a status of 'configured' in the Network
Configuration menu (GUI).

However the exact same errors are occurring in the logs.

Any ideas?

Thanks for your help.
Cyril
