The problem turned out to be that my USR was powering up (from NVRAM)
with a speed setting of 19200, but I had getty set for 38400. Getty
doesn't send an AT (and I can't figure out how to make it do so) which
means that unless the modem is in the correct state, there will be a
speed mismatch between modem and serial port. This didn't happen when
dialing OUT because the modem autobaud detected on my at commands...
Moral: Always make sure that the modem NVRAM settings match the getty's
and make sure that Seyon (or your dialout program) doesn't change the
modem's lock rate, either, or the problem will resurface whenever
someone decides to dial out.
