SBUS<sb>:UART:POLarity <Polarity>
Defines the logic levels of the bus. The idle state corresponds to a logic 1. The start bit
corresponds to a logic 0. "Idle high" (high=1) is used, for example, for control signals,
while "Idle low" (low=1) is defined for data lines (RS-232).
Suffix:

*RST: IDLHigh
Usage: Asynchronous command
Manual operation: See "Polarity" on page 357
SBUS<sb>:UART:RX:HYSTeresis <Rx hysteresis>
Sets the hysteresis for the Tx line.
