I have googled for this but am not finding anything suitable...
I have an old modem (actually modem component with a serial interface)
that I want to use to monitor an analog phone line.
I was hoping I could find some code like a "black box" that I can send
commands (AT...) to, and it would give me the responses, and any
asynchronous mesages, such as the RING message etc.
Part of the problem is this little gizmo sends some data as ascii
characters, other data is sent as binary. (FSK data for things like the
caller id info, VMWI etc.)
I would like to use Perl, or C, but was hoping I wouldn't have to
re-invent the wheel to do the basic serial communications?
Does anybody have any suggestions, or good serial comms references you
can point me to?
Thanks,
Don
