Cannot initialize modem.

Hi everyone,

Im completely new to QNX.

I have Microcom DeskPorte 56K Voice external modem connected to /dev/ser1.
When I try to connect to the internet using dialer, I get message Connection
Failed without modem even getting initialized. I personally think its
because of modem being already intialized by another program. I suspect
that, because the TR led is on, which means Data Terminal Ready status is
set. How can I close port and make modem available for dialer? Is there a
way to send ATH command to my modem before dialer starts initializing modem?


Thank you all.

You can talk to the modem with the qtalk utility:

qtalk -m /dev/ser1

(write down the escape sequence)

AT…

Ensure ATZ elicits OK for the dialer.
