It's possible for the internal modem to be partly fried (by a digital line,
for instance) and become unable to detect a dial tone. The modem may still
work in every other respect except for that one. Fortunately you can
instruct it to "blind dial" and it'll probably work fine.

The method of doing that differs depending on how you're controlling the
modem, but with Open Transport you should turn on the "ignore dial tone"
checkbox in the Modem control panel. With FreePPP there's a similar
setting. If you'd just to test, use a terminal emulator program like ZTerm
or Clarisworks and type "ATX3" to turn on blind dialing, then
"ATDT555-1212" to try and dial manually. If it works you've found the
problem - the modem can't be repaired as far as I'm aware, but it will work
fine as long as you blind dial.
