RS-232/422/485 Send_String Escape Sequences
RS-232/422/485 Send_Commands (Cont.)
TXCLR
Stops and clears all
characters waiting in the
transmit buffer.
Syntax:
SEND_COMMAND <DEV>,'TXCLR'
Example:
SEND_COMMAND RS232_1,'TXCLR'
Clears and stops all characters waiting in the RS232_1 device's transmit buffer.
XOFF
Disables software
handshaking (default).
Syntax:
SEND_COMMAND <DEV>,'XOFF'
Example:
SEND_COMMAND RS232_1,'XOFF'
Disables software handshaking on the RS232_1 device.
XON
Enables software
handshaking.
Syntax:
SEND_COMMAND <DEV>,'XON'
Example:
SEND_COMMAND RS232_1,'XON'
Enables software handshaking on the RS232_1 device.
RS-232/422/485 Send_String Escape Sequences
27,17,
Sends device-specific break
characters for a specified
duration.
Syntax:
SEND_STRING <DEV>,"27,17,<Time>"
Variable:
Time = 1-255 in 100 microsecond increments
Example:
SEND_STRING RS232_1,"27,17,10"
Sends a break character of 1 millisecond to the RS232_1 device.
27,18,1
Sets the ninth data bit to 1 on
all character transmissions.
You can use this escape sequence with the B9MON command.
Syntax:
SEND_STRING <DEV>,"27,18,1"
Example:
SEND_STRING RS232_1,"27,18,1"
Sets the RS232_1 device's ninth data bit to 1 on all character transmissions.
27,18,0
Sets the ninth data bit to 0 on
all character transmissions.
You can use this escape sequence with the B9MON command.
Syntax:
SEND_STRING <DEV>,"27,18,0"
Example:
SEND_STRING RS232_1,"27,18,0"
Sets the RS232_1 devices ninth data bit to 0 on all character transmissions.
27,19,
Inserts time delays before
transmitting the next
character.
Syntax:
SEND_STRING <DEV>,"27,19,<Time>"
Variable:
Time = 1-255 in 1 millisecond increments
Example:
SEND_STRING RS232_1,"27,19,10"
Inserts a 10 millisecond delay before transmitting characters to the RS232_1
device.
