On an 8 Mhz clone (Blue Chip PC) I can get 2400 baud up-downloads.  I have
used a few of the additional postings which ast posted a couple of weeks ago.
I do lose an occasional packet, but no big deal.  Running cron or update while
using the tty is probably a bad idea.  (Definitely bad with a big crontab!!)

IF somebody would post minix assembler code for klib88.as and mpx88.as
and make the conversion to minix compilation for Andrew Hannam's tty
driver, I would be very grateful.  According to Mr Hannam, the driver
handles 9600 quite well.  (XT or AT ???)  Also, it is supposed to have
an almost full subset of ansi as well as XON/XOFF.  IF ANYBODY has made
this tty driver run and compile under minix compiler, PLEASE -> mail
the cnanges to me so that I can try them and post them if they work.


One more suggestion to everybody...
If an article is specific to ATARI ST, it might be helpful to put the
word ATARI as the first word in the subject line so that we IBM people
know that it does not apply to us.  (An even better idea would be for
somebody to implement virtual memory for MINIX so that programs could
be as large as memory.  This would be feasable with AT computers.  XTs
would be quite slow, but at least they would run large programs.  I have a 
nasty feeling that ATARI users will post non-IBM programs.)
