Indeed, mscreen DOES use /dev/ttyp* as the devices for the pseudo tty's. The
Computone Intelliports DO NOT. These boards have their own built in drivers 
for multiscreen support on serial terminals. You do NOT use mscreen to utilize
these alternate screens under the Computone's (at least on all the Intelliports
I've used). In the ic_install script ("It's recommended") you can configure the
type of terminal support that is allowed on the line. I.E you have available
to you:

"Intellikey"

and

"Intelliscreen".

or both.

You'll want to pick the "Vanilla" terminal support entry. This will give you
the "Intellikey" and "Intelliscreen" support. Read the "/etc/ic_master" file
for more details. I believe that all you have to do is to enable the
alternate computone ports and you're on your way. To goto another screen just
hit SHIFT-F1, SHIFT-F2 etc. Check the manual for specifics. I haven't played
around with it that much but it seems to be a nice feature. We don't have
many terminals around here with memory so it's not as advantageous to us.
Even if we did it wouldn't be much good. Most of our users have a hard time
mastering logging in. 8-(

BTW, I would think that the mscreen terminals would work PROVIDED you have
enable the ttyp* ports that you wish to use. Try:

enable ttyp0

mscreen

SHIFT-F1

That should get you started.
