Re: [TCLUG:18425] RS232 keyboard

["David S. Cargo" <escargo@anubis.network.com>]

What interested me about your description was that RS-232C specifices
the 25-pin connector.  I have used as few as four wires to connect
two RS-232C ports together.

Some keyboards use a 9-pin subset of RS-232C, but I don't know that
it's a formal standard.

Searching the web I found this page:

and for the 25, 9, and 8 pin versions,
