Hi Paul,
Its an interesting quesiton I think, and I found this page which touches a
little on the topic.
http://www.cisco.com/warp/public/76/9.html
It is about attaching a modem to a console port, but it brings up some
shortfalls of the console port.
No RS232, so you will need to manually disconnect the sessions.
The EXEC session wont auto reset with a connection drop. it would have to
timeout.
Doesnt support hardware flow control.
Can only support speeds up to 9600 bos.
Lacks reverse telnet capabaility.
Cannot be used for DDR, as there is no corresponding async interface.
All that being said, I think it would be possible to get two routers to
connect through console ports if they both had a modem attached. Would just
need to think through it a bit and maybe a bit of wiring involved.
