To All,

        I have fiddled with my code for nearly 5 hours in search of any
possible bugs.  So far as I can tell, having run it through the simulator
several times, there are none.  I am trying to decode manchester encoded
data.  To detect the slopes, I am using the PORTB interrupt on change
featur.  Simultaneously, I am using the TMR0 interrupt to "time-out" if
no slopes are detected within reasonable times.  Is there a problem using
the two interrupt sources simultaneously?  Any suggestion?

Merry Christmas,
