FIL232.BAS and FILGPIB.BAS demonstrates how the command set is used to
control and filter wheel through serial or GPIB interface.

FIL232.INI contains the comm interface parameters which FIL232.BAS needs
to establish communication. This file needs to reside in the same directory
as the FIL232.BAS and/or FIL232.EXE. The setting can be changed through 
SETUP232.

FILGPIB.INI contains the comm interface parameters which FILGPIB.BAS needs
to establish communication. This file needs to reside in the same directory
as the FILGPIB.BAS and/or FILGPIB.EXE. The setting can be changed through 
SETUP488.

The exe files were compiled by QB 4.5.

A properly installed National Instruments GPIB adapter and its 
DOS driver GPIB.COM are required to run FILGPIB.EXE.

The commands for filter wheel are:

A  - Init mono/filter wheel
Z3 - Target Move
Z4 - Read Position
Z5 - Poll Busy
Z7 - Set Filter Wheel parameter (optional)

Proper syntax for these commands is shown in the source code.
