The C packet simply contains a command in its data field. The server runs
the command and sends the results back to the client, just as it would send
a file, except the file header packet has type X rather than F. If the
output of the command is short enough to fit in the data field of a single
packet, it can be sent back in the ACK to the C packet.
Why don't you take some packet logs of a failing transaction and have a look.
If you can't figure them out, send them to kermit-support@columbia.edu.
