supraexpress modems (28.8) problems w/dial-ins

Post by David Lebe » Sun, 25 Feb 1996 04:00:00


        I've configured my linux box to receive calls from two 28.8
SupraExpress modems (both support v.34).  Everything works fine, the
connection, everything.  However, when the user logs off, the modems
literally go bezerks and make the LED display shows pure garbage and
the SD/RD leds blinks relentlessly.  After that, the modem no longer
answer to commands issued by my system or to incoming calls, and I get
this kind of messages inside /var/adm/messages:

Feb 24 14:05:02 zeus kernel: ttyS0: 13 input overrun(s)

        for both ports.  The only solution is to power off the modem
and restart it.  Then, uugetty regains controls and accepts answers.

        Here's a copy of my /etc/default/uugetty.ttyS0 file:

INIT="" AT&F2S0=1\r OK

1. Problems with dialing out when dial-ins are enabled

I'm having trouble getting dial-outs to work when dial-ins are
enabled.  I can dial out on /dev/cua1 when getty isn't running
on /dev/ttyS1, but when getty is running I get a message that
the port I'm trying to dial-out on (/dev/cua1) is in use.  I
read the FAQs and everything seems to be set up right.  What
am I doing wrong?
