Now that you've all got your shiny-new TTY drivers, I've already
started receiving bug reports and enhancement requests.  Specifically,
I got a note from ast listing a few deficiencies...

(1) It produces a little bit of snow on cheap CGAs.  Yes, I know this,
and I'm going to work on it (possibly by borrowing some of ast's well-
tested code for this purpose).  I felt that the snow was minor enough
not to be TOO annoying, and that getting serial capabilities working
was quite a bit more important.

(2) It doesn't have "scroll-reverse" capabilities.  Mea culpa.  I
forgot that "mined" requires this (I use ELLE all the time these
days).  I'll post a patch RSN to take care of this.

(3) Biggest boo-boo of all:  Apparently, my console driver doesn't
work on EGAs.  Since the only machine I could test this on has a
cheap CGA, I just sort of prayed that it would work on an EGA as
well.  Could someone out there fill me in on how to set up an EGA
for CGA emulation, and on the deficiencies in said emulation mode?

On to other news, though:  After finishing with the tty driver, I
got ioctl() to work by passing the entire structure to the kernel
(This makes it possible to use all fields of a structure as well
as to add and expand structures very easily).  Using this, I then
ported "dcp" (the UUCP clone) and was able to send a mail message
via uucp from my PC to encore.  Next step is to port a mailer and
news... (and the race is on, to see who can have the first MINIX
PC on the net! :-) )
