Sending Kermit Commands
You can use an HP 48 to send Kermit commands to a Kermit server—
another HP 48 or a computer. If the HP 48 is a server, you can send
Kermit commands to it (although it only responds to GET (KGET)
SEND, REMOTE DIR, REMOTE HOST, FINISH, and LOGOUT).
The following steps assume the receiving device is already set up as a
server.
