	We're having a problem with tip under MtXinu 4.3BSD/NFS, on a
VAX-11/750, using a USR Courier on an ABLE DZ-16.  Sometimes (not always)
when we quit (using ~.) one of the 2 tip processes hangs on the read (FD,
buf, BUFSIZ) in tipout.c:tipout().  Since tip has opened the ACU for
exclusive use, that hangs the line until somebody comes along and kills the
process.  I don't think there is anything wrong with the modem or other
hardware because uucp is able to dial out on that line without any
problems.

	I tried slogging through the tip code, but I must confess I really
can't figure out what's going on (or at least not all the nitty gritty
details).  Has anybody seen this before?
