----------
No. Let me explain because the Kermit protocol is unlike FTP.
You can say SET FILE COLLISION ? to see what options are available
when receiving a new file with the same name as an existing one. Option
DISCARD rejects the new version, OVERWRITE accepts the new, and so on.
TCP sends a complete list of files to the client, which is quite
a memory problem, and then the client requests each file in turn from that
list. In the middle of that operation the client can prompt you yes or no.
The Kermit protocol avoids such lists and the file sender decides which file
to send, one after the other, and the name of each is sent with each file.
Thus the file sender is the only agent knowing which file will be sent next.
