Hi !
I have to establish qtalk connection between two QNX 4.25 ’ PC through a
modem.
On the “other” site I set up into the sysinit file the following:
->tinit -c"modem" -t /dev/ser3 &

On “my” site I use the command( I use ser3 also on my site) :
->qtalk -Tqnx -m/dev/ser3 client
where client is to be fetched from /etc/config/qtalk and I wrote there:
→ client ATDTXXXXXXXX

After I issue the qtalk command, modem starts to dial-up and gets
connection, so I have the message :

CONNECTED …

And that’s it no login , nothing. I tried to send some chars , then I
received ATA, ATZ and so on.
Could you please help me !! I thing I am somewhere close to the truth,
but…?

The “-t” should be “-T”. I suspect the modem was doing the answering,

not the OS. To avoid that, you can configure the receiving modem
with ats0=0. Also check flow control - you usually want hardware
flow control. The User’s Guide has quite a detailed section on all
this.

Dear Richard !
Thank you very much for the advices. Although I managed to establish
connection under my scheme. There were some specifical for this modem
commands, which I implemented into the dialing string ( ATX3DTWxxxxxxxx@). It
runs now O.K.
Thank you again Richard for your readiness to help !!!
Regards !
