Modem In Use message while trying to qtalk

Hi all,

When I try to talk through a serial port through qtalk, I get a “modem in use” message.
I looked for any older qtalk sessions that could be open, but did not find any.
This is a tested procedure that has been working but the first time this has failed. (the Rs-232 cable has been Ohm tested, and it is connected to serial port 2)
The machine has been rebooted many a times.
the command used is:
qtalk -e -b 9600 -m /dev/ser2


“stty < /dev/ser1” should only say 1 open for stty itself. If there are more than one, You need to use “sin fd” etc to find out who has it open.

Will this work in QNX 4.25?
