My original question was:
OK, here's an easy one for you:
SUN OS 4.1.4 ( I know I wish it was something else)
IPC
MultiTech modem
It was working till 3 days ago. We were able to dialin with no problem.
Now impossible to do anything with this modem. when we call the modem
will answer but will not give a prompt.
I checked eeprom:
ttyb-rts-dtr-off=false
ttyb-ignore-cd=true
ttya-rts-dtr-off=false
ttya-ignore-cd=true
I beleive it's OK.
I recreated the dial-in/out device:
cd /dev
mknod cua0 c 12 128
chmod 600 cua0
chown uucp cua0
mv ttya ttyd0
I checked the gettytab:
#
# Fast dialup terminals, 2400/1200/300 rotary (can start either way)
#
STD9600|Fast-Dial-9600:\
:nx=D2400:tc=9600-baud:
D2400|Fast-Dial-2400:\
:nx=D1200:tc=2400-baud:

:nx=D300:fd@:tc=1200-baud:
5|D300|Fast-Dial-300:\
:nx=D2400:tc=300-baud:
the ttytab looks as follow:
# @(#)ttytab 1.7 92/06/23 SMI
#
# name getty type status comments
#
console "/usr/etc/getty cons8" sun on local secure
#ttya "/usr/etc/getty std.9600" unknown off local secure
ttyd0 "/usr/etc/getty STD.9600" dialup on remote secure
#cua0 "/usr/etc/getty D9600" dialup off remote
secure
ttyb "/usr/etc/getty std.9600" unknown off local secure
tty00 "/usr/etc/getty std.9600" unknown off local secure
I run #kill -HUP 1
the serial port has software carrier detect disabled.
/etc/rc file has the following entry:
/usr/etc/ttysoftcar -a > /dev/null 2>&1
my /etc/remote file looks as follow:
dialup1|Dial-up system:\

But when I run the following command:
ttysoftcar -a
The system will hung
I don't know what I am doing wrong. Please help.
And thanx in advance.

The solution by Vince Hickey:
I have seen this problem on LaserWriter Printers too... I solved the
"hang"
problem with ttysoftcar -y /dev/ttya or ttysoftcar -n /dev/ttya. It
appeared that different scenerios would put the port in a wierd state
and even a powerdown did not help. Try the -y first then the -n (or
visa-vera one may free it up) This information was located in a Sun
Tech Note sometime back in 1990 (?) I happen to remember this VERY
troublesome issue.
I Hope that fixes it.
