for those who still use minicom to connect to a console (serial) port on a cisco (or whatever) device: i prefer “screen”, because its so easy, and for the most things it’s all you need.
screen should be already pre installed with ubuntu, with osx it’s easy to install using macports.
to use it, just type:
$ screen /dev/ttyS0 9600
where: ttyS0: is your serial device 9600: is the baudrate
to close the session you have to press ctrl-a k and then y (for yes)
Screen has a lot more functions and is a very useful program. Maybe i’ll find time to write about it sometime later.
