I only found one minor bug in the Ultiterm vt52 implementation--It has a
destructive backspace.  (Rogue doesn't work.  huh?  wah?  vi?  oh yea--I guess
that too.. :-)  I also wish it had that 2-space indent--I'm stuck with a shabby
b/w tv until I'm rollin in the dough, so...

Bryan, writing an xmodem routine in BASIC wouldn't be very hard at all.  Xmodem
is not very complicated--I have the stats laying around here somewhere.  (ask
if interested.)  It's mostly:
             1 byte Start-Of-Header
             1 byte block #
             1 byte compliment (255-blk#)
           128 bytes of data
             1 byte End-Of-Block.

This is not totally correct, but the point is, it is quite simple.  Just listen
for nak, ack, and ctrl-x (abort.  is this nak?).  What I don't get is why you
want to do this is BASIC.  At LEAST use BASIC09!  Oh well, yer decision--
WrWrite for the stats on xmodem or for me to write a BASIC xmodem.

Appeal to ALL:  Anyone got zmodem/kermit stats?  ANSI info?
Thanks,
      Jon
