This is another one of those things that I do not do very often. And when it comes up, I have re-invent the wheel. No more. I will have here.

This was done from a CentOS 6.x machine connected via a Cisco console cable to a 35xx switch. This configuration has worked for any Cisco equipment I have worked with as well.

If minicom is not installed:

# yum install minicom

Setup minicom.

# minicom -s

Configure the serial port by selecting “Serial port setup” from the menu.

Select the serial port using A:
A (ttyS0)

Configure the port connection by selecting E:
C (9600)
V (Bits)
L (Parity)
W (Stopbits)

9600 8N1

Toggle the hardware flow control:
Hardware Flow Control (off):

This will save the configuration as the default configuration:

Save setup as dfl

Ensure that user accounts that need to access the console are added to the dialout group.

# vigr


Verify your terminal emulation. Mine was set to xterm, and none of the menuing worked. Obviously, this would need to be done in the user environment.

# export TERM=vt100

Another useful setting is the toggle to enable logging. This is very useful, especially when messing a router or switch configuration.

From the menu (CTRL-A Z), enable capture using L.
