001-5006-000_FCC.docx Page 29The Mode drop down menu configures the communications mode for the Primary and Secondary PCPort.See Table 2-6 for Communication Modes configurations.Table 2-6 Communication ModesMode DescriptionSync/ESC with No HS Sends data using Sync/byte-stuffing protocol without handshaking.Buffered with No HS Sends buffered data without handshaking (this mode required for DOXoperation.)Sync/Esc with RTS/CTS HS Sends data using the Sync/Esc byte-stuffing protocol with RTS/CTShardware handshaking.Buffered with RTS/CTS HS Sends buffered data with RTS/CTS hardware handshaking.Sync/Esc with Flow Control HS Sends data using the Sync/Esc byte-stuffing protocol with flow controlhandshaking.Buffered with Flow Control HS Sends buffered data with flow control hardware handshaking.2-9001-4006-1012.5.3 Port StatisticsFigure 2-7 Port Statistics ScreenPort Statistics show current parameters of the PC‟s Primary and Secondary COM Ports.Baud RateBaud Rate shows the current baud rate setting for the Primary and Secondary COM ports.RTSRTS shows the current state of the RTS (request to send) line. RTS is an output from the PC.DTRDTR shows the current state of the DTR (data terminal ready) line. DTR is an output from the PC.CTSCTS shows the current state of the CTS (clear to send) line. CTS is an input to the PC.DSRDSR shows the current state of the DSR (data set ready) line. DSR is an input to the PC.DCDDCD shows the current state of the DCD (data carrier detect) line. DCD is an input to the PC.2-10001-4006-101Bytes Tx‟edBytes Transmitted shows the number of bytes (characters) transmitted since the port was last opened orcleared.Bytes Rx‟edBytes Received shows the number of bytes (characters) received since the port was last opened or cleared.
