SERIALPROTOCOL
Sets the protocol to be used by a serial port
Platform: OEM729, PwrPak7
On some OEM7 receiver cards, selected ports can support either RS-232 or RS‑422 signaling protocol. The default protocol is RS-232. The SERIALPROTOCOL command is used to select the protocol (RS-232 or RS‑422) supported on the port.
RS-422/RS-232 selection is available only on COM1 of the OEM729 or COM1 and COM2 on the PwrPak7.
