Hello,  I have recently been working on a program that I run in my
.logout just before I do an stty 0 (I have to do the stty 0 because
if I leave stuff running in the background when I logout, UNIX hangs
onto the terminal, and we have about 7 different machines that are
all accessed through the same terminals).  The problem is that this
program writes some stuff out to the screen, then exits, then the
stty kills the terminal after only about half of the stuff has been
written out.  I have been given the suggestion that I could just pause
for a few seconds, but that is klugy, and if I then go to a slower
terminal (I regularly use 9600baud, and 1200baud, but sometimes 300),
I will have to increase the delay, and I want the terminal to become
free for other users as quickly as possible.  I know that there is an
ioctl that will see if there is any pending input, but is there a similar
one for output (I have looked, but I can't find it).  I have tried flushing
the files before I exit, but that doesn't help.   HELP!!!!!

                  Thanks,

                      S. John Banner
