mgetty DTR problems.

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hi,

I am getting pretty desperate, so I hope that you can help me. I think
I've tried about everything, read the FAQ, the manual, tried the
mailing list archive (but the DNS won't resolve it, so that one didn't
work) but I can't make mgetty work correctly.

My problem is that mgetty works correctly for every first connection to
a modem, but doesn't accept any further calls. On bootup mgetty sees the
modems, and the DTR light flashes on. On an incoming call the program
for authentication (/bin/login or pppd for /AutoPPP/) is called correctly
(I am sure about this for login, not quite sure for PPP since I haven't
been able to get this working because of authentication and/or ipnumber
allocation problems. But that's another problem, and I don't think I
should bother the list with that).

Once the user logs off, the DTR light goes off and doesn't come up
again. The lock file in /var/lock remains, and mgetty doesn't do anything
anymore with the port.

I am using Linux with kernel 2.0.38, mgetty 1.1.21. I've tried two
different types of modems with the same result. The modem I want to use
is a Cyber Bullet E56K RVP modem yes, this modem can do a lot more that
I want to. I only want to use the modems for dialing in. This is my
last tried configuration:

mgetty.config:
-------------------
debug 9
speed 115200
data-only y
init-chat "" ATQ0E1V1H0 OK ATL0M1S0=0 OK AT&K3&D2 OK
force-init-chat "" ATQ0E1V1H0 OK ATL0M1S0=0 OK AT&K3&D2 OK
-------------------

login.config:
-------------------
/AutoPPP/       -       @       /sbin/pppd
-------------------

I used logger to redirect the mgetty logfile through syslog, loglevel 9, so
logger means the logfile of mgetty.

The Log:

Oct 13 09:58:16 sde0 PAM_pwdb[25]: (login) session closed for user eric 

After this a new mgetty session is forked by init, but it doesn't
to anything. I doesn't log a thing, it doesn't remove the lock file,
doesn't reinitialize the modem. Nothing, it just sits there.

I think I've given all the information required, but please let me know
if there is anything else I forgot to mention. I really need this to work.
