Thanks. Waiting for 100 msec is a bit long, does it also work when
waiting for 20 msec? I guess any time will do so long as we give the
terminal a chance to get some CPU time.
stoptermcap() is also used for shell commands. If someone has a shell
command in his startup script then tcflush() might cause a problem.
It might help to call it only when exiting.
