A10s-4GB Android - UART2 not working?

According to https://www.olimex.com/wiki/A10s-OLinuXino-MICRO, UART2 (which is on the UEXT connector) is mapped to /dev/ttyS1.  However, "busybox stty -a /dev/ttyS1" results in "stty: /dev/ttyS1: Input/output error" and "cat /dev/ttyS1" gives me "/dev/ttyS1: invalid length".

Also I get "stty: /dev/ttyS2: Input/output error" for ttyS2 which I believe is mapped to UART3.

Any suggestions?


That's probably true for Linux.  Maybe not true for Android?  (Remember Android is not Open Source.)

You may need a fex setting for what you want.
