Nevermind the name difference. Look up the proper COM name in device manager,
and use /dev/com7 (adjust the number as needed).

Note that Cygwin 1.5 only maps 16 serial devices (this is a problem for me as
the crappy Toshiba Bluetooth software assigns a gazillion of Bluetooth COM ports
it never needs and I never configured...), in doubt just remove an unused one
(preferably one with a low number) in device manager and unplug and re-plug your
USB to serial converter, Windows should then assign the lowest untaken number
automatically.
