Update HardwareSerial.h with 9-bit definitions
Browse files Browse the repository at this point in the history 
I added all the combinations of 9-bit serial.
9N1, 9N2, 9E1, 9E2, 9O1, 9O2, 9M1, 9M2, 9S1, 9S2
This allows newer processors like the RA4M1 to use its built-in 9-bit support. 9Bit is widely used on many industrial and embedded machines, and having a true 9-bit UART brings a high value add to these boards.
