[ale]Killing all processes on a port

[Chris Fowler]

I looked at the source.  It trates the tty as a file and walsk through /proc
to locate
the correct process.  I wish there was another way.  I'm sure there is and
I'll do a little more
research.

By 'attached to', you mean a tty that you're not currently sitting in
front of?  For that I'd use fuser - for example fuser -k /dev/ttyS01
I have fuser -k /dev/tty  setup as a speed key on my CRT at work, just
for the reason you mention.

 Meaning you want to write some C code that does this, or this is part
of another program?  I don't know C, so I don't know if fuser will work
in that context.  I'll let someone else answer that.
