Is it possiable to have two rfcomm modules loaded at the same time, each one
with a different PSM values? What I was attempting to do was to modify
rfcomm/core.c and recompile it into a new module, but it seems it is not as
simple as that as can be seen by this kernel Oops while unloading the
module.

Has anyone done something like this before?

I don't really understand what you are trying to achieve, but I think
you should try it without putting RFCOMM on another PSM.

I had hoped to be able to "pick-up" data sent to the 2nd RFCOMM Module
(using a new PCM value to differentiate it from the "Original") and pass it to
another program to transport it across the network to another PC where it
would be "injected" into a modified module there. At the moment, I am only
loading the modified module, and it not absolutely necessary that both be
loaded at a time, but would be interesting to do.

this is not possible this way. It needs more changes to provide such a
functionality and you must keep it inside the RFCOMM module. Why do you
need it?
