4.8.3. Morse Dialog: Switch Acceptance Times
By setting the switch acceptance times in the
Close
and
Open
columns, you can minimize the effects of
accidentally pressing or releasing switches. The
Close
time is the minimum time a switch must be pressed
before it is acknowledged. The
Open
time determines how long the software will wait after a switch release
before acknowledging it. These times can be set independently for the
Dot
,
Dash
, and
End
switches.
4.8.4. Morse Dialog: Audio Feedback
Most people like to hear some audio feedback while they are using the Morse code input method. Hearing
your dots and dashes can be especially helpful when you are first learning to code. Use the
Audio
drop-
down menu to set how your Palmtop device will indicate each switch activation. If you select
Blip
, then your
device will play back a different pre-recorded sound for each switch. This mode is most useful for fast coders
using two or three switches. If you select
Tone
feedback, then your device will play back a different tone for
each switch. The tones will persist as long as you hold down the switch. If you are using a single switch, the
tone will switch from dot (high) to dash (low) after the
Dash
time has elapsed. If you select
None
, there will
be no audio feedback.
In traditional Morse code, there is no sound to indicate the end of each character. However, having an "end-
of-character" sound can be very useful when coding. If the
End Sound
button is checked, you will hear a
short pre-recorded sound after the end of each character, even if the audio feedback is set to
None
.
If you select a sequence of dots and dashes that does not correspond to a valid code, your Palmtop device
will play a special error sound to let you know. The error sound will only be disabled if the
Audio
drop-down
menu is set to
None
and the
End Sound
box is not checked.
All audio feedback is played using the "private" volume. See section 4.9 for more information.
4.9. Options Dialog: Speech Tab
Your Palmtop device supports speech synthesis through the DECtalk and Acapela software speech
synthesis. You can use the synthesizer to speak individual characters, words or sentences. Or you can
select exactly what and when you want to speak. The
Speech
dialog is accessed by selecting
Tools >
Options
and then selecting the
Speech
tab.
