Hmm, I was not aware of this bug, but it looks like Jim has confirmed. I
really can't think of why this would have changed with the build machine
rebuild, as it ended up nearly identical to the original.

This will result in the drop-down box looking strange for people. Can
you please abstract out the act of changing the name? So, for testing,
you should test the augmented name, but add just "COM10" to the ports
list. Then, we need some indirection again when we go to open the port
that they select. Presumably we should just add an opens_serial_port()
method to the Platform like list_serial_ports().

Can you take care of that?

Jim, could you test that manually typing in the above pattern allows you
to get to COM10+ on your box?

Thanks!
