I put in a 100nF chip cap for the problematic V+ cap and put in a new
MAX3232.  No joy.  Same results.  150mA current draw and a warm chip.
Could both of my chips be bad?  I've never had this bad of luck since
I put a chip in backwards.  PICs hate that.

I've got more coming in a few days.  Maybe I'll proto a good old MAX232
and trust the tolerance of the lpc2106. :)

Cheers,
David
