This Field Specifies Configure by Doing the Following

Delete mode	Select how the controller responds to
	a delete character.

Select Ignore, CRT, or Printer. If you select Ignore, the controller ignores the delete character. If you select CRT or Printer, the controller ignores the character it received immediately before the delete character. The controller then sends a signal to the CRT or printer to erase the deleted character. Select CRT or Printer only if you enable the echo mode.

XON/XOFF	Whether or not you want XON/XOFF	As the controller receives characters, it constantly determines how many
	enabled	more it can receive without losing any. When XON/XOFF is enabled, the
		controller sends a “stop sending character,” XOFF. If the sending device
		has the XON/XOFF feature, it stops sending characters. When the
		controller has more room, it will send a “start sending” character (XON).
		Select ENABLED or DISABLED.
Echo	What the controller should do when it	If you disable the echo mode, characters received by the controller are
	receives an ASCII delete character	sent only to the echo counter and not to an output device, such as a CRT
		or printer. If you enable the echo mode, the controller sends any
		characters it receives through an ASCI read or read line instruction to a
		waiting output device. For example, if you want the controller to print a
		message to a LED marquee, enable the echo mode.
Termination 1	The termination characters you	Enter a maximum of two characters (hexadecimal).
Termination 2	defined	Use termination characters with the ASCII Read Line instruction or with
		the Test Buffer for Line (ABL) to indicate a line has been entered.
		The default character is the ASCII equivalent for [RETURN], 0x0D. You
		can also use the ASCII equivalent for LINE FEED (0x0A). To specify no
		character, enter \FF.
Append 1	The append characters you defined	Enter a maximum of two characters (hexadecimal).
Append 2		Use append characters with the ASCII Write with Append (AWA)
		instruction to indicate the end of a line. Append characters are the last
		characters sent after a line of information.
		The default characters are the ASCII equivalent for [RETURN] (/0D) and
		LINE FEED (/0A). To specify no character, enter \FF.
