Hmm, I can only test up to COM16. Cygwin allows names up to /dev/ttyS63
and converts them up to \\.\com64. The conversion works, but the Windows
function to open the device fails when I use ports > \\.\com16. Which
makes sense, given that only COM1 - COM16 exist on the system.
Sorry, but you're on your own here. Somebody who has more ports has to
debug this. http://cygwin.com/acronyms/#PTC
