I have a TRENDnet 56K (V.92) High Speed Internal PCI Data/Fax/Voice Modem. I want to dial a phone number, wait for a second and then have the modem hang up.
I am using the dialing string of "ATM0DT15555555555,;H"
The call goes through fine but the Hangup doesn't happen after the string is dialed. I have to issue a second command of "ATH0". This same dialing string as above works on other modems I have used but for whatever reason it is not working here. I have tried several variations of the dialing string (long and short pauses) but it seems like whenever there is a ";" it doesn't execute the commands that follow.
