Using the RS-232 link in receive-only mode

To place the SDM‑SIO2R into RS-232 receive-only mode, use the SerialOpen() instruction with the SerialOpenFormat value set within the range of 64 to 79. Consult SerialOpen() for more detailed information about these settings.

In receive-only mode, the SDM‑SIO2R will consume less current than normal but can still receive new information on its RS-232 port.

The following example will set the SDM‑SIO2R with address 0 into receive-only mode. All normal baud rates and buffer sizes are supported.
