I am trying to get the COM port resources values (such as I/O Range) as
given in Device Manager->Ports (COM & LPT)->Communication Port->(right click
& get)->Properties Page. On this Properties page we get Resources tab at the
last. In this tab, we find "Resource Settings". In this we have "I/O Range".
For COM1 generally it is shown as "03F8 - 03FF".
I would like to know which Windows DDK API (like SetupDi, CM_ calls) or SDK
API provides a means to obtain this information programmatically?
Thanks in advance.
