SEND_STRING Escape Sequences
The EXB-COM2 and EXB-MP1 support several special SEND_STRING escape sequences. If any of the
character combinations listed below are found anywhere within a SEND_STRING program instruction, they
will be treated as a command and not the literal characters.
Use the ESCSEQON and ESCSEQOFF NetLinx SEND_COMMANDS to control whether these are active
or not. The ESCSEQON command must be precede the Escape Sequences, otherwise the strings will be
processed normally.
EXB-COM2 & EXB-MP1 SEND_STRING Escape Sequences
Command Description
27,17 Send a break character for a specified duration to a specific device.
Syntax:
27,17,<time>
Variable:
time = 1 - 255 (measured in 100 microsecond increments)
Example:
SEND_STRING RS232_1,"27,17,10"
Sends a break character of 1 millisecond to the RS232_1 device.
27,18,0 Clear the ninth data bit by setting it to 0 on all character transmissions.
Used in conjunction with the 'B9MON' command (page 37).
Syntax:
27,18,0
Example:
SEND_STRING RS232_1,"27,18,0"
Sets the RS232_1 device's ninth data bit to 0 on all character transmissions.
27,18,1 Set the ninth data bit to 1 for all subsequent characters to be transmitted.
Used in conjunction with the 'B9MON' command (page 37).
Syntax:
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.
27,19 Insert a time delay before transmitting the next character.
Syntax:
27,19,<time>
Variable:
time = 1 - 255. Measured 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.
27,20,0 Set the RTS hardware handshake's output to high (> 3V).
Syntax:
27,20,0
Example:
SEND_STRING RS232_1,"27,20,0"
Sets the RTS hardware handshake's output to high on the RS232_1 device.
27,20,1 Set the RTS hardware handshake's output to low/inactive (< 3V).
Syntax:
27,20,1
Example:
SEND_STRING RS232_1,"27,20,1"
Sets the RTS hardware handshake's output to low on the RS232_1 device.
