Actually, I just checked the source for Cygwin 1.5.5 and they are using /dev/comX as an alias for /dev/ttySX (search for "ttyS" in the winsup/cygwin/dtable.cc Cygwin source file). Still, their main goal was to allow one to use serial ports in the same way one would under Linux:

Also, I see no situations where the source is handling the serial port differently among the different versions of Windows. So it appears the serial ports are used in the same manner among all Windows platforms.

The /dev stuff isn't real well documented on the Cygwin website (as they admit) and so the Cygwin source is really the best place to get info on this subject. I just happened to be digging through it a few months ago.
