Managing your network devices via console

Cisco makes a 16 port Async card for ISR routers, they even bundle it
with a 2811 router for fairly inexpensive $$$...  Cisco2811-16TS is the
partnum I think
You can scale up very high or down very low for your console needs with
cisco routers, and inexpensive used or obsolete routers are available
for not much money.
The octal cables are available with rj45's already on them, which is
nice.... Email if you want a sample term server config for a 2800

If Cisco is not what you want... Consult the Zonker's Greater Scroll of
Console Knowledge: ... You may find
what you are looking for there.
