NXC-COM2 Dual COM Port Control Card

NXC-COM2 Send_Commands (Cont.)

Command	Description
HSON	Enable RTS (ready-to-send) and CTS (clear-to-send) hardware handshaking.
	Syntax:
	SEND_COMMAND <DEV>,"'HSON'"
	Example:
	SEND_COMMAND RS232_1,"'HSON'"
	Enables hardware handshaking on the RS232_1 device.
RXCLR	Clear all characters in the receive buffer waiting to be sent to the Master.
	Syntax:
	SEND_COMMAND <DEV>,"'RXCLR'"
	Example:
	SEND_COMMAND RS232_1,"'RXCLR'"
	Clears all characters in the receive buffer waiting to be sent to the Master.
RXOFF	Disable the transmission of incoming received characters to the Master (default).
	Syntax:
	SEND_COMMAND <DEV>,"'RXOFF'"
	Example:
	SEND_COMMAND RS232_1,"'RXOFF'"
	Disable the transmission of incoming received characters to the Master (default).
RXON	Enables sending incoming received characters to the Master. This command is automatically sent by the
	Master when a 'CREATE_BUFFER' program instruction is executed.
	Syntax:
	SEND_COMMAND <DEV>,"'RXON'"
	Example:
	SEND_COMMAND RS232_1,"'RXON'"
	Start transmitting received characters to the Master (default).
SET BAUD	Set the RS-232/422/485 port's communication parameters.
	Syntax:
	SEND_COMMAND <DEV>,"'SET BAUD <baud>,<parity>,<data>,<stop> [485 <EnableDisable>]'"
	Variables:
	Baud: baud rates are: 230400, 115200, 76800, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600,
	300, 150.
	Parity: N (none), O (odd), E (even), M (mark), S (space)
	Data: 7 or 8 data bits
	Stop: 1 or 2 stop bits
	485 Disable: Disables RS-485 mode and enables RS-232/422
	485 Enable: Enables RS-485 mode and disables RS-234/422
	Note: The only valid 9 bit combination is (baud),N,9,1.
	Example:
	SEND_COMMAND SOMEDEVICE_1,"'SET BAUD 115200,N,8,1, 485 ENABLE'"
	Sets the SOMEDEVICE port's communication parameters to 115,200 baud, no parity, 8 data bits, 1 stop
	bit, and enables RS-485 mode.
