[BNM] Redirecting one Unix serial port to another?

[John Montgomery]

Don't know about redirecting serial ports, but the unix command "tee"
can be used to redirect stdin to a file as well as passing it through
to stdout.  e.g.

 tail -f /dev/tty.my_bluetooth_serial_port | tee bt.txt

Would write everything into "bt.txt" as well as to the terminal.
