* Execute command through a Communication-Channel

* hXcv [i] The Handle to work with
* pszDataName [i] Name of the command to execute
* pInputData [i] Buffer for extra Input Data (needed only for some commands)

*
* Minimal List of commands, that every Printmonitor DLL should support:
*
*| "MonitorUI" : Return the Name of the Userinterface-DLL as WSTR in pOutputData
*| "AddPort" : Add a Port (Name as WSTR in pInputData)
*| "DeletePort": Delete a Port (Name as WSTR in pInputData)
