Sorry to say, the answer is probably a bus mouse.  "Polling" the serial port
on a timesharing system just isn't smooth.  There is a new VP/IX coming out
for SVR3.2.3 which may help some.

>2) Keyboard lockup when running vtlmgr and ksh (in gmacs mode).

Haven't seen that on SVR3.2.x, but I haven't tested it much since ksh
is not part of the base Unix system until SVR4.  I use ksh in emacs mode
on SVR4.0 and have not seen lockup.

Echo "\033[1c" (escape, open-bracket, one, c) to the console.  Zero sets
it back to underline, 2 sets it to invisible.  (Documented in display(7))
Vi and anything else that issues a "tput reset" will change it back;
you could modify your terminfo for AT386 and change the initialization string.
