That very well may be, so let me explain.

What I want is the ability to set up a modem for dial in purposes (uucp
logins, user logins) AND still be able to use the modem for dialing out
(uucp, tip, etc).  Under 386BSD 0.1 + patchkit 0.2.2 this wasn't possible
until I switched over to cgd's bidirectional com driver.  So my question is,
with the stock NetBSD 0.9 com driver, is what I mentioned above possible?
And if so, how?  Is it accomplished with a program like comcontrol (which
cgd provided with his driver) or it is enough to set up two devices for the
same port?

From the mail I've received, I understand this is not a problem with
FreeBSD 1.0, but I've had conflicting responses concerning NetBSD.
