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:

that sets the beep pattern to three.
