/dev/ttyu0 is for mainboard UART
/dev/ttyU0 is for USB UART adapter

Only root has read-write permission for these devices. User account gets access
denied.

I can do a root account loopback test (join pins 2 and 3 of the DB9 connector)
so that whatever is typed is sent on TX and received on the RX pin using
Minicom or Picocom.


If I do "chmod g+rw /dev/ttyu0" it works for the user account.
