	I am happy to contribute yet another in the continuing
collection of UUCP bugs.  This one is in conn.c, dialup().
immediately (a couple of lines) after the open of the phone
line (not the dialer), there is a "ioctl (..., ..HPCL,..)",
which is setting the hangup on close bit.  There are several
things wrong with this.  First, there is already a HPCL ioctl in
fixline() which is call a couple of lines later (1 or 2).
Second, if ioctl is being faked with a gtty/stty combo, this
will do a stty speed 0 on the port which will cause a real
hangup on some (maybe all) UNIX's.  We noticed this when we
swapped out our last DZ for a DH, speedier modem control I
guess.

PS.  This bug is in all versions of UUCP that I have seen.
