    DATA ENTRY This section gives a brief description of serial data communication conditions and handshaking protocols supported by the C82307* /C82308* interface card. Serial data communications The C82307* /C82308* interface allows you to select either RS-232D, RS-422A, or 20-mA Current-Loop signal

    is once again ready. This protocol can be performed under either RS-232D, RS-422A, or 20-mA Current-Loop signal levels. The C82307* /C82308* interface card sends an X-on (11H) code when it is ready to receive data, and an X-off (13H) when it is busy. The X-on/X-off signals
