Comm Control - Dial tones
Hi Brock,
If you want to send tones after the initial dial command, terminate that
initial dial command with a semicolon (as in "ATDT3035551234;" & vbCr).
This keeps the modem in command mode so that subsequent commands can be sent
to it. If these subsequent commands also dial, they, also, need to be
terminated with a semicolon.
You mention "connect" in your question. The modem cannot send tones after
it has connected with another modem, so I assume that you meant to say,
"after the called telephone has answered."
For more information on this subject I suggest that you get a copy of my
book. See below for the link.
