Adjust serial port settings (speed, flow control, timeouts etc).
Serial port settings
- Speed: COM port speed in bauds (bits per second).
- Initial RTS/DTR state: specify RTS/DTR state after opening COM port. If not defined, default value will be used.
- Buffered reading mode: if enabled, reading from COM port is optimized to use less CPU but may introduce small delays.
- Retry write requests on failure: if enabled, write requests will be repeated until they are successfully completed.
- Ignore write requests if buffer is full: if enabled, write requests to COM port will be ignored when output buffer is full.
- Merging write requests: if enabled, multiple write requests data will be merged into single request.
- Purge COM port buffers on open: if enabled, COM port buffers (input and output buffers) will be purged. This can be useful to remove stale data in input buffer.
