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.

27,20,0 Sets the RTS hardware

handshaking output to

Low/Inactive.

Syntax:

SEND_STRING <DEV>,"27,20,0"

Example:

SEND_STRING RS232_1,"27,20,0"

Sets the RTS hardware handshaking output to Low on the RS232_1 device.

27,20,1 Sets the RTS hardware

handshaking output to

High/Active.

Syntax:

SEND_STRING <DEV>,"27,20,1"

Example:

SEND_STRING RS232_1,"27,20,1"

Sets the RTS hardware handshaking output to High on the RS232_1 device.
