G. Custom Delay
Custom Delays are defined "on-the-fly" in duration. A 4-digit character,
58xx
, defines the
custom delay. The two digits following the
58
, shown as
xx
, represent the duration of the
delay in tens of milliseconds.
Although custom delays can be placed anywhere in a beep message, they go well with
custom beeps if you need to create a truly unique or specialized signaling burst. For
example, a string of custom beeps and custom delays could be used to generate a string of
ASCII characters of the proper tones for use with modems.
H. Gap Characters
Gap Characters are used to introduce a silent period between beeps. Ten (10) gap
characters have been defined from 10 ms to 320 ms using the codes
60
through
69
. Gap
characters may be used alone to separate groups of beeps, or they can be automatically
placed after every beep by using the
Automatic Gap On
code (described later). Note that
any time a gap character is entered, the Message Handler remembers its duration. When
the
Automatic Gap On
character is encountered, the Message Handler will use the
duration that it remembered from the previous gap character. This is also true of the
Custom Delay character. This parameter is not changed at the end of the beep message.
I. Beep Duration Change
Beep Duration Change characters are used to set the duration of the beep characters that
follow. Ten (10) duration change characters have been defined from 10 ms to 320 ms
using the codes
70
through
79
. The beep duration may be changed as often as desired
within a beep message (even between each beep).
Note that any time a beep duration change is made (including a Custom Beep), the duration
will be remembered by the Message Handler. When any succeeding beep is encountered,
the Message Handler will use the duration that it remembered from the previous duration
change.
This parameter is not changed at the end of the beep message.
J. Automatic Gap On
The Automatic Gap On character,
56,
causes the Message Handler to place a gap between
each beep. The duration of the gap depends on that last gap that was encountered. It
defaults to 10 ms upon a cold start.
K. Automatic Gap Off
The Automatic Gap Off character,
55
, causes the Message Handler to send the beeps that
follow in a series without any gaps between them.
