13.4 Programming Limitations
Any combination of a key defined to be a double key and either a SHIFT, CTRL, ALT or Fn key is not supported.
This limitation is due to the way the basic keyboard is constructed and is derived from the fact that certain three
key combinations cannot be detected by the keyboard controller software.
This limitation is due to the way the basic keyboard is constructed and is derived from the fact that certain three
key combinations cannot be detected by the keyboard controller software.
Each programmed key has the ability to generate up to 20 different scan codes. Depending on the key selected
and it’s shift/alt/ctl state, this can represent as few as 5 or as many as 20 different keys.

Details of the command/data structure required to setup the keyboard will use proprietary extensions to the
existing PC keyboard command/data port. These commands are subject to change. (Typically, only the utility
program that sets up the keyboard will use this interface.)
