I am working on my 3 window g protocol for fsuucp, and am having a problem
with checksumming that i hope some uucp guru can help out with.

The g protocol description says that if a packet is a control packet
(k = 9), then the checksum bytes C0 and C1 contain  a zero, and the value
of C, respectively.

That's not what i'm getting... i get:

  k = 9
 c0 = 107
 c1 = 42
  c = 63
  x = 119
len = 0

obviously, 42 != 63, and 107 != 0... so, when i run this through the
checksum validator, it comes up false. Does anyone know what i'm doing
wrong? Is there some magic value i should be using? should i ignore the
checksum on control packets if the xor check is ok? Haaaaalp!! :-)
