Reaching back into my old BBS days.......

....  If you read/write directly to the COM port a modem is attached to,
you can send an "ATDT" command.
If there is no dialtone, you should get a "NO DIALTONE" response quickly
(5 seconds).
If there IS dialtone, you will most likely get a NO CARRIER response
after the timeout.

... And I think the timeout register is S7.   So to something like this:

ATS7=3
ATDT

Should give you a response in 3 seconds or so...
