"sudo ps ax | grep rfcomm".

The comnmands wc and cat are "freezing" because they work but no data is coming over the rfcomm port.

Did you try the original fix

Create a flie with the line:
KERNEL=="rfcomm", GROUP="dialout"
in a flie like /etc/udev/rules.d/rfcomm.rules

And are you running karmic or jaunty?
