Send_String Escape Sequences

The AXB-232++ does not regard certain three-character combinations within a Send_String program as literal characters, but as commands. The following table lists those combinations.

Send_String Escape Sequences

27,17,<time>	Syntax:
Sends a break character of	"27,17,<time>"
the specified length of time.	Variable:
	time = 100 microsecond increments 1 - 255.
	Example:
	SEND_STRING AXB232,"27,17,10"
	Sends a break character of 1mS.
27,18,1	Syntax:
Sets the ninth data bit to 1 for	"27,18,1"
all of the following characters	Example:
to be transmitted.
	SEND_STRING AXB232,"27,18,1"
	Sets the ninth data bit to 1 for all of the following characters to be transmitted.
	Used in conjunction with the 'B9MON' command.
27,18,0	Syntax:
Clears the ninth data bit to 0	"27,18,0"
for all of the next characters	Example:
to be transmitted.
	SEND_STRING AXB232,"27,18,0"
	Clears the ninth data bit to 0 for all of the next characters to be transmitted.
	Used in conjunction with the 'B9MON' command.
27,19,<time>	Syntax:
Inserts a delay before the	"27,19,<time>"
next character to be	Variable:
transmitted.
	time = 100 microsecond increments 1 - 255.
	Example:
	SEND_COMMAND AXB232,"27,19,10"
	Inserts a 1mS delay before the next character to be transmitted.
27,20,0	Syntax:
Asserts RTS hardware hand-	"27,20,0"
shake output high.	Example:
	SEND_COMMAND AXB232,"27,20,0"
	Asserts RTS hardware handshake output high.
27,20,1	Syntax:
Asserts RTS hardware hand-	"27,20,1"
shake output low.	Example:
	SEND_COMMAND AXB232,"27,20,1"
	Asserts RTS hardware handshake output low.
