Keyboard Send Control Characters
This feature is used by the Keyboard Wedge and USB Keyboard interfaces. It
specifies how the scanner transmits ASCII control characters to the host. Refer-
ence Appendix E, Scancode Tables for more information about control charac-
ters.
Options are as follows:
Send Ctrl+Key :
ASCII characters from 00H to 0x1FH inclusive are transmitted in
the format Ctrl+Key. Special keys are available in the range from 81H to A1.
Send Ctrl+Shift+Key :
The behavior is the same as above, but control keys are sent
in the format Ctrl+Shift+Keys.
Send Special Function Key :
Send characters between 00H and 1FH according to
the special function key mapping table (see "Interface Type PC AT PS/2 Alt
Mode
or USB-Keyboard Alt Mode" on page 282). This is used to send keys that
are not in the normal ASCII set. A unique set is provided for each available
scancode set.
