Very minor change to the pdp1.c source, just add the call to the dynamic loader.
If an unkiown IOT is executed, the loader is called which tries to resolve:/opt/pidp1/IOTs/IOT_nn.so and if so invokes it.
The handler implements one method and is passed the full PDP1 context, etc.
I've tested it. it works. So, now what?
Oscar, want me to send you the files?
