   :-) This time my question is Windows related, not DOS.   
      
   But if thats so, where does "GetCommProperties" get its permissable   
   baudrates data from ?  Mind you, that "dwSettableBaud" bitmask returns   
   different results for both ports (AFAIKS correctly so for the CP2102).   
   Where does that bitmask come from ?. Besides, if it can't why does it exist   
   to begin with ?   
      
   Also, the CP2102 isn't a UART, but a microcontroller acting as a bridge   
   between an USB port and a few serial lines.  It also needs to have some   
   device driver software installed to be able to use it.   IOW, /both/ could   
   contain the list I'm looking for.   
      
   Don't get me wrong: I can imagine that there might be reasons why they never   
   put such a shortlist in either the microcontroller or the device driver.   
   But if the list exists I want to know how to get at it, or get an   
   explanation to why its (still) not implemented (its existence sounds like a   
   no-brainer to me...).  I mean, its not 1987 anymore (the date of the 16550   
   UART). :-)
