Using minicom inside a screen session
By default minicom uses ctrl-a which also happens to be used by screen. If you started minicom inside a screen session and hit ctrl-a then your ctrl-a will be caught by screen. Now how to issue a minicom command? Just hit ctrl-a a. You can also use screen to connect to the serial port so that you don’t even need minicom anymore:
# screen /dev/ttyS0 38400
