You know, what would probably be a better idea would be to fix
the bug in SunOS that causes the trouble. It's still present
in 4.1.0, and has been around at least since 4.0.0. Any
comment from Sun?

In the meantime, leaving processes running after logout on modem
ports causes very confused gettys to be spawned. You can work
around this by "kill -9"ing these bad gettys. Here's a script
to do that. You'll need the latest version of sps for this
to work right. Run it from cron as often as you like.
In the meantime, the only way to run such processes is to
use batch/at or cron. Yuckola.

----- cut here -----
#! /bin/sh

PATH=/bin:/usr/local/bin:/usr/ucb ; export PATH

kill=`sps -va 2>/dev/null | awk '
    { if ( ( $2 ~ /\?ty/ ) && ( $10 == "-" ) ) print $9 } '`

if [ -z "$kill" ] ; then
exit
fi

echo Killing processes: $kill

sps -vp $kill

kill -9 $kill

exit 0
