No, it can't.  When using the Win32 device names, the files are not
recognized as devices by Cygwin but instead they are treated like 
normal files.  If you want Cygwin support, you must use POSIX device
names.  If you want to access the serial interfaces using Win32 functions
anyway, I'd suggest to use Win32 functions throughout and not rely on
Cygwin.  This already begins with using CreateFile instead of open.
