Nope, that's not a feature.  The T2500's default configuration will drop
into command mode when you send a break (S54=0), but it won't do that if
you merely send a CTRL-C.  Even if you programmed the modem to look for
CTRL-C as the 'escape' character (S2=3), it would take three consecutive
presses with a one second pause before and after.  Simply pressing it
once wouldn't do the trick.

I would guess that something somewhere is sending a break signal when you
press CTRL-C.  If you set S54=3, then the modem will pass breaks through
and not drop into command mode.  Try that and see if the problem stops.
