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
