Hello,
I have a new P4 server with a modem in it. I am using QNX 4.25D. The modem is a
US Robotics PCI version. I can use show_pci -vvv to get the port and irq for the
modem just fine. I start “Dev32.ser port,irq” in the sysinit file. I can talk to
the modem and dial out with qtalk just fine. With qtalk running, I can call the
machine and qtalk prints “RING” to the screen.
My problem is with the “modem” utility. In the past we have started modem from
a tinit line in the sysinit file. Modem does not want to answer the phone.
I have tried taking modem out of the sysinit and starting on the command line, using
the example given in the docs, “on -t /dev/ser1 modem -b 57600 -L…”. This just
locks the /dev/ser1 from being used by qtalk (“modem in use”) and when modem is
slain, qtalk stops talking to the modem (ATZ does not return OK).
What would be causing this?

FWIW, I have had similar experience in getting modems to answer. I have always managed
it though. Usually my problem has been that the number of rings is unrelated to the
settings I request. I haven’t spent too much time investigating because it is not that
critical to me. My command line is
tinit -c “modem -B 115200 -b 115200 -r 3 -L -iATZX0M0” -t /dev/ser1 &

Thank you for the information. It helps, but I still can’t get the modem to
answer.
I have the serial port set properly, (I can talk to the modem via qtalk and
ATZ returns OK)
I can get a dialtone and dial out. If I leave qtalk running and call the
number, qtalk responds
with a “RING” message.
My command line is
tinit -c “modem -B 115200 -b 115200 -r 3 -L -iATZX0M0” -t /dev/ser1 &
and is the last line of the sysinit file.
What am I doing wrong?

try running modem on its own first with debug mode…
e.g.
modem -D/dev/con6 -Lb115200 -s1
this way you will see output from modem on con6 (or wherever else you want
to see it). and a locked baud rate is best so no auto negotiate to modem
from the uart. and put a delay in (-s) so that you don’t start login too
soon.
that’s what we do here and it works well. a tricky science though…

but the modem still does not answer.
This is a brand new system installed from the June 2000 CD. (Dev.ser, 4.23I, June 27, 1997)
and modem is july 17, 1998.
qtalk -m /dev/ser1 can talk to the modem and I can dial out. The modem is a 3Com pci internal
modem.
What would be causing this?

After various combinations of hair pulling and “on -t /dev/ser1” commands, we are able to
get the modem to answer. Initially we were putting the “open consoles AND start modem” in the
same tinit line. Moving to two separate tinit lines has fixed the problem.
