Cisco 2500 Console Ports
Cisco router console ports do not support software (XON/XOFF) or hardware
(RTS/CTS) flow control. However, on all routers except the Cisco 2500
series, the console port is wired to connect RTS and CTS. This means that a
terminal using hardware flow control sees CTS in response to asserting RTS,
and communication between the terminal and the router works properly.
On the Cisco 2500 series, this is not possible. The result is one-way-only
communication between the terminal and the Cisco 2500 console port: you will
be able to see output from the router on the terminal, but you cannot type
anything in. The workaround is to disable hardware flow control on the
terminal or to strap the CTS high.

Its a hyperterm thing, play with the connection settings, emulation and such
and it should start working. I've seen where Hyperterm is set to auto and
it detects the emulation wrong and I have also seen where hyperterm is set
correctly and is doesn't work unless set to auto. At very least download
the free hyperterm upgrade, or better yet find a better term program (at
leat thats what everyone says, I try not to rely on other programs since you
can't take anything with you to a CCIE lab you might was well learn on the
minimum)
