[BNM] Redirecting one Unix serial port to another?

[John Montgomery]

Though on 2nd thoughts it might be that you can use a symbolic or
hardlink to make /dev/tty.my_bluetooth_serial_port and
/dev/tty.my_USB_serial_port the same file.  Not sure, as I'm not quite
au fait with how the "deviceness" of the files will make things more
complex.

So what are you actually trying to do?
