Programming
RS-232/422/485 Send_Commands (Cont.)
HSON
Enables RTS (ready-to-send)
and CTS (clear-to-send)
hardware handshaking.
RXCLR
Clears all characters in the
receive buffer waiting to be
sent to the Master Card.
RXOFF
Stops transmitting received
characters to the Master Card
(default).
RXON
Starts transmitting received
characters to the Master
Card.
SET BAUD
Sets the RS-232/422/485
port's communication
parameters.
TSET BAUD
Temporarily sets the RS-232/
422/485 port's
communication parameters.

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 Card.
Syntax:
SEND_COMMAND <DEV>,'RXOFF'
Example:
SEND_COMMAND RS232_1,'RXOFF'
Stops the RS232_1 device from transmitting received characters to the Master
Card.
This command is sent automatically when issuing a CREATE_BUFFER
Send_Command.
Syntax:
SEND_COMMAND <DEV>,'RXON'
Example:
SEND_COMMAND RS232_1,'RXON'
Sets the RS232_1 device to transmit received characters to the Master Card.
Syntax:
SEND_COMMAND <DEV>,'SET BAUD
(Baud),(Parity),(Data),(Stop) (485 DISABLE/
ENABLE)'
Variables:
Baud = 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400 (factory set
default), 57600, 76800, 115200
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-422.
485 Enable = Enables RS-485 mode and disables RS-422.
Example:
SEND_COMMAND RS232_1,'SET BAUD 9600,N,8,1 485
ENABLE'
Sets the RS232_1 port's communication parameters to 9,600 baud, no parity, 8
data bits, 1 stop bit, and enables RS-485 mode.
Syntax:
SEND_COMMAND <DEV>,'TSET BAUD
(Baud),(Parity),(Data), (Stop) (485 DISABLE/
ENABLE)'
TSET BAUD works the same as SET BAUD, except that the changes are not
permanent, and the previous values will be restored if the power is cycled on
the device.
