Serial implementation of the Port class.
See the Port class documentation for how to use the common API.
- Note
- Under Windows, the timeout resolution is milliseconds, not microseconds. The timeout value will be rounded to the nearest millisecond when used.
- Options
- device <string>
- Serial device to use.
- Default: /dev/ttyS0
- parity none|even|odd
- Data parity.
- Default: none
- baud <integer>
- Baud rate. Valid values are 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 34800, 57600, 115200, 230400.
