NetBSD 1.0 (at least) will not let you talk to the modem unless
CD is set high on the modem.  This is great if you have tty02
turned on in /etc/ttys but this doesn't help tip very much.  If...

/usr/bin/cu -l /dev/tty02 -s 38400

fails, or

echo "AT" > /dev/tty02

hang the terminal (be sure to have another terminal to kill it),
CD is your problem.

***DESIGN REQUEST ON***
It sure would be nice if one could talk to a serial port when it is
not in use or CD is low.  One can't even do an
echo "AT&C1&D2/N0S11=60" > /dev/tty02
to initialize the modem!
***DESIGN REQUEST OFF***

Don't get me wrong, I love NetBSD and recommend it to all of my
friends, but this is one issue that just make me hang my head...

I've been beating on this problem ever since I first hit NetBSD
and still haven't got a good reason for this "feature".

No, you don't want to do that, then your as bad off as before.

Boot a DOS diskette (or partition) run your favorite DOS comm
package, connect to the port and type the magic init string...

AT&C0

This will force CD high until the machine is powered down.

If you want to save this setting to NVRAM, type...

AT&W0

Hummm...SuperaExpress 14.4, this isn't one of the RPI based
modems?  If it is, it doesn't have NVRAM, so don't power down
too often.  :-)
