I recently bought a pair of T2500's and couldn't get them to work other than
in PEP mode.  Turns out that the basic non-PEP modem is mounted internally
as a daughter board and this daughter board frequently comes loose in shipment.
If you're having problems with a T2500 in non-PEP modes (like it talks to you
just fine but doesn't send any tones), pick up your modem and shake it.  If
you hear something going "clunk, clunk", the daughter board has come loose
internally and you'll need to open up the modem and re-seat the board after
which everything will work just fine.

Hopefully Telebit has taken action to fix this problem with some better
mechanical design on more recent production models of the T2500!
