Are you sure you're using the correct com port?

That's just another one of the many fun and wonderful little
bits of brokenness in MS Windows. COM14 can't be opened using
the name COM14. You have to call it \\.\COM14. Using the
unadorned COMx name only works for COM1-COM9. Since the
dimwits at MS decided to use C's "escape" character as a
directory separator, you've got to double it up (e.g.
"\\\\.\\COM14") to get the string you really want.

What it displays as on other computers is irrelevant. Just
because a USB serial adapter shows up as COM14 on machine A,
that doesn't mean it's going to be COM14 on machine B.

Go look in the device manager to see what com port you should
be using.
