I am working on an AS/400 to a credit card
authorization network. Unfortunately no previous AS/400 has previously certified
to this network. I'm hoping someone else has seen
this requirement for async communications. The specs from the other system call
for me to add an LRC code at end of packet,
"each record must be immediately followed by an
LRC character that is computed by using the XOR function on each character of
the record. This is a data integrity check." The network person on the other
side is not able to really describe what it is. Sounds like some sort of
check digit for the whole packet. Any ideas?
