un-dedicating a line to a dialer

[Dave Sherman]

I have the source to programs I wrote in C called "originate" and
"answer" which do exactly what howard (alt at aids-unix) suggests -
check whether the line is free, and switch the /etc/ttys entry
and signal init. I know there are more elegant ways which
have been posted in the past, but this was easy and works without
any kernel changes or lock files. It's been running since April
on lsuc with no problems.

If anybody is interested I can mail them to you or post them to net.sources.
