We can't be responsible for the restrictions of Procomm. MS-DOS Kermit
lets you choose any packet length up to the theoritical maximum of 9024.

The packet length is determined by the file receiver. In other words,
the receiver gives the sender permission to send packets UP TO the given
length; the sender can choose to send less, but not more. A real Kermit
program will normally use the length that you tell it. If you were using
MS-DOS Kermit, the command would be:
SET RECEIVE PACKET-LENGTH 2000
or whatever. Evidently your version of Procomm does not want to receive
long packets, no matter how you "hexedit" your Procomm configuration.
Maybe that's why it does not have a "command" or setting for this.
Give the same command to C-Kermit when uploading. The current version of
C-Kermit is 5A(190) and, like MS-DOS Kermit 3.xx, it is a full
implementation of the protocol: long packets, sliding windows,
compression, locking shifts, etc etc.
