FW: Reading responses from Modem.

Thanks for the responses.  I will look into using PySerial for talking to
the modem as suggested by Peter.  The code example I gave is probably not
the best way to do it, but it seemed to work ok (after running the
diagnostics program).

How do I "test for the modem prompt" and "confirmation after any outputs"?
Any pointers as to "the correct way" to dial a number and read the responses
from the modem (ie to see if the number was dialled, busy tone detected,
etc.).

Any help is greatly appreciated.
Etienne

	Which means NO \r\n wanted...

	Safest would probably be a sequence (not in Python here)

		flush, sleep, write, flush, sleep

	I also note that the original posted code does not seem to be
testing for the modem prompt or confirmation after any outputs.
