Cisco and minicom

Connecting to a Cisco router or switch is really easy using a terminal application called minicom, if you use minicom solely for this purpose you can do a system wide setup (as root) like this:
# minicom -s

Or make sure /etc/minicom/minirc.dfl contains this:
pr port /dev/ttys0
pu baudrate 9600
pu bits 8
pu parity N
pu stopbits 1
pu rtscts No

And make sure you add the dialout secondary group to the appropriate users:
# usermod -G dialout pmjdebruijn
