Is there any reason we restrict the Windows serial device names to 
"COM?" A user could have serial boards, com ports higher than 9 
(\\.\COMX), or weird file devices that act like serial ports.

The following patch removes the code that rejects devices that don't 
start with the word "COM".

Comments?

Cheers,
Carlos.
