I know I can set the serial port baud rate. What is the number of data bits, stop bits, and parity. Are they fixed or can they be changed
Are they fixed or can they be changed
Fixed, at least up to 1.0.1. Though there are plenty of examples of the library changes need to support different values.
So if they are fixed, then what are they.
The default is 8 bits, no parity, one stop bit.
Edit to correctly say "one" stop bit.
