ok i think i got it?
Pinpointing the Problem
You can’t communicate at all. Is the problem Kermit, the PC, the port, the connector, the
cable, the other computer, or something else? There is an easy way to narrow this down:
the loopback connector. A loopback connector plugs into your serial port. It has no
cable. Inside the connector, the receive and transmit signals are connected. This means
that whenever the PC sends a character, it immediately receives the same character.
Loopback connectors are available from computer supply catalogs and computer stores. If
you can find one, connect it to your port, and then run the following test:
__________________________________________________________________
A>kermit (Run MS-DOS Kermit)
MS-Kermit>set port 1 (Select the right port)
MS-Kermit>set local off (Let loopback do the echoing)
MS-Kermit>connect (Begin terminal emulation)
abcdefghijklmnopqrstuvwxyz (Type some characters)
Alt-X (Escape back to the PC)
MS-Kermit>exit (Exit to DOS)
A>
