How does one configure the UART for custom data/parity/stop bits? If you give an example, can you make it 115200/16/none/1? OS is raspbian on A+
The 115200, none, 1 part can be done with the stty command (man stty).
The standard drivers/UART do not support 16 bits.
However don't expect a great deal of reliablity at 115200bps.
