Not as far as I know. The only known difference is that the modem port
will support an external clock on two of the DCD/CTS pins, and the printer
will only support an external clock on one (though a clock on the other
will screw things hideously).

Right. Since you're using dtrcts flow control, the computer can't hang up
the modem using DTR. The stock getty assumes the modem gets hung up on
exit, which it doesn't. mgetty might help here.

Try not setting dtrcts and see if things are different. It could be that
the modem's not doing handshaking when it really ought to. If the modem
hangs up when you log out, you know it's not doing the dtr side of the
flow control, so you need to either find a modem manual (mine's still
hiding; though my car finally does start again after much effort Saturday
:-) or use rtscts (which leaves DTR out of it).

loosing random text sounds like the modem's not dropping CTS when it
should. Adding random text is weird; are teh modem cables ok? Maybe a
dying wire is getting intermittent and noisy?

Right. You're setting 'local' again. Without local, with a good cable and
ok modem config, the login banner won't go out until the modem's answered
the phone. Remember, lots of modems echo stuff when they're off line.
That's what you're seeing. That's why 'local' can be turned off. :-)

Take care,
