Minicom
From FrogspawnWiki
To have minicom work properly for Cisco (and similar) devices you need two things - a config and an alias.
Config
The config firstly sets the port and comm settings.
You should create a file in /etc/minicom called minirc.cisco, it should contain the following:
pu port /dev/ttyUSB0 # or whatever your serial port is pu baudrate 9600 pu bits 8 pu parity N pu stopbits 1
You can now use that config by typing minicom cisco
Alias
The alias is going to disable the modem initialization (-o) and enable linewrapping (-w)
alias minicom="/usr/bin/minicom -o -w"
added to your .bashrc (or equivalent) (maybe /etc/bashrc for global) will have the desired effect, however you may want to go one further
alias ciscoterm="/usr/bin/minicom -o -w cisco"
That will get you minicom running with your cisco profile in a single command.
