For example, if the terminal type is PCAT (US), then the first element of the WedgeSetting$
can be defined as follows,
Wedge_1$ = CHR$(1)
5.9.3 Capital Lock Auto-Detection
If "Capital Lock Auto-Detection" is enabled, the SEND_WEDGE function can
automatically detect the capital lock status of keyboard when the keyboard type selected is
PCAT (all available languages), PS2-30, PS55, or Memorex Telex. If this is the case, the
SEND_WEDGE function will ignore the capital lock status setting and perform
auto-detection when transmitting data. If "Capital Lock Auto-Detection" is disabled, the
SEND_WEDGE function will transmit alphabets according to the setting of the capital lock
status.
If the keyboard type selected is not one among PCAT, PS2-30, PS55, and Memorex Telex,
the SEND_WEDGE function will transmit the alphabets according to the setting of the
capital lock status, even though the auto-detection setting is enabled.
To enable "Capital Lock Auto-Detection", add 128 to the value of the second element of
WedgeSetting$ (Wedge_2$).
5.9.4 Capital Lock Status Setting
In order to send alphabets with correct case (upper or lower case), the SEND_WEDGE
function must know the capital lock status of keyboard when transmitting data. Incorrect
capital lock setting will result in different letter case (for example, 'A' becomes 'a', and 'a'
becomes 'A').
To set "Capital Lock ON", add 64 to the value of the second element of WedgeSetting$
(Wedge_2$).
5.9.5 Alphabets Case
The setting of this bit affects the way the SEND_WEDGE function transmits alphabets. The
SEND_WEDGE function can transmit alphabets according to their original case (case
sensitive) or just ignore it. If ignoring case is selected, the SEND_WEDGE function will
always transmit alphabets without adding shift key.
To set "Ignore Alphabets Case", add 32 to the value of the second element of
WedgeSetting$ (Wedge_2$).
