'
'This class has software functionality for DPP (DP4, PX4) Device
'Configuration management. The clsDPPConfig Class is the main repository
'for DPP device configuration data. The clsDPPConfig Class can store and copy
'a DPP device configuration. The current DPP device configuration can
'also be saved to a string for display.
'
'The clsDPPConfig Class does processing of configuration data
'for transmission to a DPP device. The processed configuration buffer can be
'transmitted to the DPP by serial communications port or by USB.
'
'The clsDPPConfig Class also stores and processes status messages and
'live spectral data requested from a DPP device.
