Ok, so I've read thru the archives and have come to a reasonable
solution for getting my event, which is as follows:  'or' the two input
lines together onto one external interrupt pin, then wire each separate
input line to its own GPIO. My ISR can then check which line raised the
interrupt and can receive the data;

My problem now is how do I get that info back into java, if my native
ISR is reading the data off the port pins, and I then return to java
'RETI' I just cannot think of a way to do this simple thing... Aaargh
please help me!

Thank you in anticipation of your prompt helpful reply which I know
someone out there is just itching to give me!
Daniel
