How do I issue DTMF tones (to interact with an Interactive Voice Response (IVR) System?
PCTTY for Vista as of the tty20080720.zip download file also has DTMF tone capability for interaction with Interactive Voice Response (IVR) systems. Simply hold down the CONTROL key and strike a number key (or # and *) at the same time, and a DTMF tone will be issued from the PCTTY program. Normally you will be listening for baudot tones from the other phone when you issue a DTMF tone. For the rare times when you are issuing baudot tones and you queue up a DTMF tone, the DTMF tone may not fully emanate from the voice modem. If this is a problem then simply let the baudot tones finish playing (the OUT meter on the right top of the screen goes blank and the IN meter next to it goes red) and then issue the DTMF tone command (CONTROL-1 etc). The DTMF tone will fully play when you do this. Why doesn’t the HELP work in Vista? Vista doesn’t run 16 bit programs and the HELP version is very old in PCTTY and is actually a 16 bit program. Sorry. You need a Data/Fax/Voice modem for PCTTY, not a Da
