Minicom is a serial line terminal emulator that allows you to take control of your board through the RS232 line. With it you can have access to the U-Boot/Linux console of your APF without needing to connect a keyboard/screen to the board. (For more informations on remote console)
On *Ubuntu / Debian
$ sudo apt-get install minicom
or use your system's graphical package manager.
To avoid using sudo or root, add your user (here mylogin) in dialout group:
$ sudo adduser mylogin dialout
then close and re-open your graphical session, to make group changes taken into account.
$ minicom -s
- Choose serial port name, parameters (8N1) and no hardware handshake
- Save config as default
- To launch it (-o to not send modem AT init sequence):
$ minicom -o
- To switch from terminal mode to command mode:
CTRL + a then z
- To quit:
Switch in command mode q
