This is a red herring.  It is not going to work:

"It won't recognize it as a serial device."

-mno-cygwin and native win32 apis really have little bearing on Cygwin.

I'm regenerating a snapshot which translates /dev/ttyS0 -> //Global??/COM1 and
/dev/com1 -> /??/com1, using the same "symlink" as is used by the windows api.

I would appreciate it if you could try the snapshot when it becomes available
and report if both /dev/ttyS5 and /dev/com6 work as you expect.
