Also with a Mega?

What version of pduino are you using? Most current is 0.8.

Also, if an older version of pduino worked fine with the Arduino Mega,
what version was that?

What happens if you specifically send 'pinMode 45 output, digital 45
1'? Or you use any other pin that seems to be not working correctly
with your setup. Also, there is 'pinState' message for querying the
current state and there is the 'capability' message that triggers a
report of all supported modes of all pins. So, I would like to know if
the non-working pins report of themselves to support 'output' mode.
Then, if you set their 'pinMode' to 'output', do they actually report
their 'pinState' as 'output'?

Ok, so you can be sure the board is working.

I don't own an Arduino Mega and I don't know how well [pduino] is
tested with that board. I certainly haven't tested it ever. 
This makes it hard for me to reproduce the problem. If you can give a
hint that the problem is in the software, that would help.
