The first time you open minicom, open it as root, set your port settings and save as setup default.

  • minicom -s
  • type A and set the path (for example: /dev/ttyUSB0 or /dev/ttyS0 )
  • next, set the baudrate to 115200 8N1 with no Hardware / Software Flow Control
  • "save setup as dfl" to save as default

In the future, start minicom using

minicom -m
Now you can type:
  • alt-q to quit
  • alt-o for options (change the port etc)
  • alt-e for local echo
  • alt-a to append line feed
