What if I edit the code and recompile? I don't know how the modem tells
the software that the connection is data .. if it outputed "DATA" or
something, I think mgetty could be configured to wait for that ... it does
for "FAX" (I think)

Will mgetty automatically handle fax if the modem outputs "FAX"?

with mgetty or in general? It seems that Silent Answer Plus is probably
fairly reliable because it checks for a certain tone - data callers need
to send "ATDT^#######" when dialing.. the hat makes the special tone.

Does it say 'reading dialin.config'? I tried using just "!all" in the
dialin.config file to ignore every call, but it still picked up the phone.
(I do have the ring count setup right, ATS0=0)
