Ok, Andy, I'll post the tty driver after I modify it to run with the normal
fs.  
And if there is enough of a interest I'll post my multi-tasking fs, I
already have a couple of people interested, so I'll probably do it.

I am sorry for a short (I hope) delay in my posting the stuff, I am struggling
with this stupid 286 XT board...

oh, a question I'll throw out: working with my serial tty and a very crude
cu program, I dialed up a BBS the other day. The port seems to lose characters
now and then when a large burst of characters come at once. I've traced down
the reason to the console handling routines, they spend lots of time in there
with interrupts off. I saw no particular reason for this so I took out the
"cli" in a couple of places. The ports work now, but the system is unstable;
it hangs up at times, once it trashed a disk. I've stuck the "cli"s back
in but am I wrong in assuming that save/restore saves and restores the
machine state exactly? Am I missing something? Oh, my problem is worse
probably because of the EGA fixes I put in (Larry Hubble's)... The screen
is scrolled with interrupts off!
