Raghu,

Harnam needs to output through the serial port the following:

P0.0 switch closed output a 30H
P0.1 switch closed output a 31H
P0.2 switch closed output a 32H
P0.3 switch closed output a 33H
P0.4 switch closed output a 34H
P0.5 switch closed output a 35H
P0.6 switch closed output a 36H
P0.7 switch closed output a 37H

I think this will require a lookup table.
