PHdialer and the ATM0 command (speaker off)

I have a ISDN modem and it does not have a speaker and therefor it
does not like a “ATM0” command, and will return a “ERROR”.

See here is my problem, PHdialer will send one to my modem when I try
to connect to the internet.

My modem returns a “ERROR” and PHdialer says “connection fail” :-/

Is there a way to stop PHdialer sending that “ATM0” command?

How about another dialer program?

I’m using the Windows install of QNX-RTP.
