I have found that to use a modem on a FreeBSD 2.0A system, one must configure
the modem to force CD high all the time.  This makes it a hassle (and a little
tricky) to swap modems between FreeBSD-2.0A and other systems.

Is there any particular reason that CD must be high for FreeBSD 2.0A to
talk to the modem?  Is this a bug, or is it this way by design?

It would be nice if FreeBSD 2.0A (like 1.1.5.1R) dealt with modems in
a more "standard" way.  Part of what makes it tricky to switch modems
back and forth between CD-high and "normal" mode (for use on multiple
systems) is the fact that when using 'cu' to talk to the modem on the
FreeBSD system, entering the modem command to switch to "normal" mode
causes 'cu' to die with a "signal 1 - user defined signal".   This means
that to switch modems between systems, one must actually have a third
system, or a dumb terminal, nearby... otherwise there's no way to make
either of the systems talk to the modem to change mdoes!

Thanks in advance,
Bill
