It’s signaled similar to QAM. Far more complicated than GPIO type stuff. Think FM radio / spread spectrum rather than bitbanging / old school serial / parallel ports. Similar to old school modems if the line is noisy it can drop to lower “baud” rates. You can manually try to recover higher rates if the noise is gone but it’s simpler to just reboot. |
