If you would like to configure Cisco router using Linux or FreeBSD (connected to a local COM port). Use the following instruction to configure device:
1) Connect cisco router to com port using serial cable
2) Use program like minicom (type minicom at a shell prompt)
$ minicom
3) Select the port, speed and /dev/ttyS0 as com1 port and save configuration as dfl. Next select Exit
4) Continue with your router configuration…
5) For more information on minicom read man page here

Hi Sir,
How r u. This is Mithun.
I’m very happy,you back again.
At this time me and Vishwas undergonig with CCNA.
This article most helpful for me.
My email-id – gaikwadmithun@yahoo.com
Thank You.
I realize this is an old post but I’ve made it my mission in life that whenever someone mentions minicom I’ll spread the good news of screen. Every admin should know GNU screen already (if not, go look it up) and it turns out that you can run ‘screen /dev/ttyS0′ and it takes care of setting up all of the speeds/etc. Plus you can disconnect and leave it running if you’re interested in catching log messages, etc.
Thanks man.
its really helping..
Hi everybody,
My problem looks like this: after establishing the connection with minicom, cu, cutecom or gtkterm my laptop (IBM T42 in the dockstation II) sends every 8 seconds “AT” string and after about 4 seconds “^Z” string.
In Exmp:
Cisco#AT
Translating “AT”
% Unknown command or computer name, or unable to find computer address
Cisco#^Z
Cisco#
Cisco#AT
Translating “AT”
% Unknown command or computer name, or unable to find computer address
Cisco#^Z
Cisco#
Cisco#AT
In that situation only cutecom allows me to work somehow (for example write an enable pass for privilaged mode). So the problem lies in configuration of the Ubuntu system 8.04 2.6.24-21.42-generic which I am using.
I would be very glad for any suggestions.
Thanks in advance,
JWedrowycz
