RS-232/422/485 SEND_COMMANDs (Cont.)

Command Description

HSOFF

Disable hardware 

handshaking (default).

Syntax:

SEND_COMMAND <DEV>,"'HSOFF'"

Example:

SEND_COMMAND RS232_1,"'HSOFF'"

Disables hardware handshaking on the RS232_1 device.

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 RS232_1 device's receive buffer waiting to be sent

to the Master.

RXOFF

Disable the transmission of

incoming received 

characters to the Master.

Syntax:

SEND_COMMAND <DEV>,"'RXOFF'"

Example:

SEND_COMMAND RS232_1,"'RXOFF'"

Stops the RS232_1 device from transmitting received characters to the Master.

RXON

Start transmitting received

characters to the Master

(default).

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'"

Sets the RS232_1 device to transmit received characters to the Master.

SET BAUD

Set the RS-232/422/485

port's communication 

parameters.

Syntax:

SEND_COMMAND <DEV>,"'SET BAUD

<baud>,<parity>,<data>,<stop> [485 <Enable | Disable>]'"

Variables:

baud = baud rates are: 115200, 76800, 57600, 38400, 19200, 9600, 4800,

2400, 1200, 600, 300, 150.

parity = N (none), O (odd), E (even), M (mark), S (space).

data = 8 data bits.

stop = 1 and 2 stop bits.

485 Disable = Disables RS-485 mode and enables RS-422.

485 Enable = Enables RS-485 mode and disables RS-422.

Note: The only valid 9 bit combination is (baud),N,9,1.

Example:

SEND_COMMAND RS232_1,"'SET BAUD 115200,N,8,1 485 ENABLE'"

Sets the RS232_1 port's communication parameters to 115,200 baud, no 

parity, 8 data bits, 1 stop bit, and enables RS-485 mode.
