No, no, no.  When in Rome, ...

Here's the important link to the User's Guide:
http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-posixdevices

Cygwin is a POSIX layer, as such it provides a POSIX view to the
supported devices.  If you use native Windows device names, the
special POSIXy handling of the device won't kick in and you are on
your own.  If you want the entire thing, use the POSIX device name.

Having said that, what you want is either /dev/st0 or /dev/nst0.
Note that st0 and nst0 have a different meaning!
