Hi Frank.  I'm trying to continue to track down this hanging problem
and am having a problem using gdb.  This problem has plagued me for a
while, and I just haven't figured it out.  If I telnet into a NetBSD box,
either Sparc or I386, and I run gdb, gdb somehow screws up my stty settings
such that I cannot type into the process.  If I exit gdb, using q^j, my
stty settings may or may not be restored to something usable.  
Does anyone have any ideas on what's going on here and how I might fix it?
(debugging and examination are dificult in the session in question.)
-thanks
-Brian

P.S.  The first script shows stty settings before and after invoking gdb.
The second shows stty settings on the pty running gdb from another window.
-thanks
