Thanks. At this point it's going to be a good week or two until I get the
serial cable so I was trying to learn as much as I can without being able
to turn them on.

Thanks. I have read different comments on this, some people seem to vacuum
their boxes out all the time with no ill effects but I was always afraid to
try it for the reason you said. As a result my equipment gets dusty fast
inside and I don't really know how to deal with it. Compressed air doesn't
seem to get things nearly as clean as a vacuum would do and these new (old)
servers are super clean inside. I don't know if the fans were blowing all
the junk out or if they lived in a filtered room or what, but they are some
of the cleanest boxes I have ever seen and they're from 2003 and 2005 afaik.

I should have known Emacs would have a terminal mode. I didn't even think
of that. I don't have a BSD system at the moment, I have been moving stuff
around. I have Solaris 10 on Intel and a Slackware Linux box as my two main
workstations. I have minicomi, screen, and emacs on my Slackware box
already so I guess I'll try those. I'm lucky to have a serial port on these
Intel boxes, a lot of the new ones don't and I have heard mixed reviews on
the usb/serial converters.

Thanks for the help everybody.
