But that's really only a convention. I think you can even do:

  mknod /dev/didyouhearthiscoolstory   c 4 64

which should create a new character device node that will be
equivalent to /dev/ttyS0 - the first UART serial port (this is all on
Linux).

So I guess a file dialog that could filter based on major and minor
numbers of device nodes would be neat - but it's probably not portable
on non-UNIX systems.

Does anyone know of such a dialog?
