Function/Control Key Support in Wedge Mode
The TriCoder, when in keyboard wedge mode or serial PC Terminal mode, can
transmit Function, Control, Alt and Shift Keys for use with software programs
that use these keys for menus or commands. For example, when the TriCoder
reads a bar code containing the Code 39 characters for SOH (Control-A), it will
transmit the corresponding function key, F1 to your computer.
These "keys" are created by combining two Code 39 characters. In order to
read them and have them interpreted as the correct keystroke, the bar code
reader must have "Full ASCII Code 39" reading enabled. The following
chart shows the encoding scheme for both IBM and Macintosh computers.
