At least on my Cygwin installation under Windows XP the serial port
is accessible as "/dev/ttySx" (x is "0" for COM1, "1" for COM2 and
so on). All the USB to serial converters I am aware of are virtual
COM ports on Windows which means that they are accessible the same
way, e.g. if the virtual COM port is "COM7" it can be be accessed
as "/dev/ttyS6",
