Clear all characters in the
receive buffer waiting to be
sent to the Master.

Description
Syntax:
SEND_COMMAND <DEV>,"'HSOFF'"
Example:
SEND_COMMAND RS232_1,"'HSOFF'"
Disables hardware handshaking on the RS232_1 device.
Syntax:
SEND_COMMAND <DEV>,"'HSON'"
Example:
SEND_COMMAND RS232_1,"'HSON'"
Enables hardware handshaking on the RS232_1 device.
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.
Syntax:
SEND_COMMAND <DEV>,"'RXOFF'"
Example:
SEND_COMMAND RS232_1,"'RXOFF'"
Stops the RS232_1 device from transmitting received characters to the Master.
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.
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.
