Absolutely; people do it all the time to set up milking machines for
serial console access. Bear in mind that if you use a 2501 or any
other router where you're on the aux port, you're limited to 38.4kbps.
It also kicks the snot out of the CPU, since the interface controller
is an 8530 and kicks out one interrupt per character received...
A 2511 or similar will have a set of Cirrus CD2430 quad serial port
controllers (in the case of the 2511, 4 of them for 16 ports total)
and be able to go up to 115Kbps. The Cirrus chip is a lot smarter
than the 8530 and does DMA (I think), and doesn't kick an interrupt
every char.
Basically, here's how you set it up:
line aux 0
no exec
transport input all
then telnet to the router, port 2001... or 4001... or 6001,
depending on what kind of characteristics you want from the telnet.
See CCO for more information.
