Hi all you mgetty wizards,
After reading the FAQ's and the mgetty-1.1.x documentation i could not
solve the problem on my own, so the last chance to get the job done is
posting a help message in this newsgroup.
I need help with the following problem:
I have to setup a remote *dial-in* connection using a SupraFAX Modem
V.32bis on /dev/ttyS1 (COM2). I use an Intel PC running Linux RedHat 5.2
(2.0.36). After doing the appropriate changes in /etc/inittab,
/etc/mgetty+sendfax/mgetty.config i rebooted the PC and tried to test
the dial-in connection with a seperate PC/modem. The following happened:
When dialing in (using the Hyperterminal (hyperterm.exe) on a Windows
NT4.0 workstation with a second analog FAX) i receive the string
"CONNECT 14400" and sometimes lots of unreadable characters, and at
least the message NO CARRIER. The connection is terminated. I do not
receive any login information (e.g. from /etc/issue). Using debug level
9 i tried to figure out what happened, but i was not able to find a
solution. (excerpt of logfile is appended). I suppose my modem has
problems when going off-hook but on the oter side i'm not sure if my
config files are correct or not. (I could not find any examples for a
mgetty.config file dealing with dial-in!)
Now here are my questions:
Q1: do i need an init-chat sequence (in /etc/mgetty.config) for
*dial-in*, or is this done only by using the answer-chat?
Q2: where can i specify any additional modem AT commands which mgetty
should use to initialize the modem? (e.g. L[123], X[1234], ...)?
Q3: where can i find what init sequence mgetty uses to setup my modem?
Is it the force-init-chat sequence?
Q4: Has anyone got working /etc/mgetty.config files for *dial-in*
support?
Q5: Does anyone have a suggestion for my problem. Is my modem broken
(old BIOS???)
Well i've to say i'm not a modem expert, hence i want to appologize if
my questions are too stupid.
Any help is gratly appreciated, please respond via e-mail.
May thanx in advance
Thomas
