Using the N/EF Character
The N/EF character provides additional control for a message than just a control character alone.
The control character determines whether an N/EF character is required. It also determines
whether this N/EF character represents a numeric quantity or an expanded function.
Use the numeric quantity character for the following circumstances:
•
specifying the beep pattern for the DOS terminal
•
changing the automatic transmit buffer length
Use the expanded function character to perform such tasks as:
•
turning sequence numbers on and off
•
calling up a stored form
•
toggling the LDS Plus ReturnToWand parameter
Here is an example of an outbound message showing the location of a N/EF character:
C is the beep pattern character
that sets the beep pattern to three.
