I ran across a nasty little problem when hooking up
my atari ST as a terminal to my NeXTstation. I followed
the instructions for the cables and installed the magic line in
the file /etc/ttys and everything worked really well.
The line is:
ttya "usr/etc/getty std.19200" vt100 on secure
The problems came the next day. I turned on the NeXTstation for some
hefty debugging and left the Atari off.
When running a program I noticed how slow it went. It got only about
50-60% of the CPU. with a ps -agx the culprit was shown to be getty
which had used already 55 minutes (the kernel had 60 minutes idle time
and I had been using probably about 20 min. for the rest).
When I turned on the Atari the increment in time for getty stopped.
One theory is that there is a going up and down of login messages
being interpreted as usernames and passwords.
The question is:
How do I stop this without pulling the cable between the computers
and without being forced to turn on the atari when I don't need it?

Thanks in advance
