Dunno. Sounds like it should work. If the modem is able to go off hook, it
"knows" how to accept commands, and how to assert the phone line. Maybe the
tone generator is broken? Does it dial if you ATDP rather than ATDT? Since
pulse dialing should use the same mechanism as is used to get the line in the
first place, the thing should have no excuse for not clicking, even if it won't
bleep.
