[comp.sys.atari.st] Uniterm 2.0c XMODEM bug

pes@ux63.bath.ac.uk (Smee) (04/14/88)

I found the following in my mailbox today, from Simon Poole (via Stephan
Leicht).  Not going to bother with it myself, since I don't use XMODEM,
but if you want to have a go...  (Amazingly, it seems to have retained its
format in transit thru several mailers. :-)

Whoops, there is a bug in the code for caculating the checksum
in UniTerm's (2.oc 008 and 009) XModem (CRC work's ok), to fix
change the sequence

      064000FF

(only occurs once) to

      024000FF

for the more nervous here's a few more bytes around the problem..

      660C
      D019
      064000FF
      51CBFFF8
      4ED0

                              Sorry
