This document explains what to do when output from the router can be seen on the console screen, but nothing that is typed in can be seen.

There are no specific prerequisites for this document.
The information in this document is based on the hardware:
The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.
The terminal is set to use Ready To Send/Clear To Send (RTS/CTS) flow control.
On all other routers, the console port is wired to connect RTS and CTS so even though you are not doing real flow control, the terminal sees CTS in response to asserting RTS.
Due to the RJ45 -> DB25 adapter wiring for the 2500, this is not possible.
Disable hardware flowcontrol or strap CTS high.
