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.
