Lpc2000

Anders,

Great to hear you got your board working! I have not tried upping the 
voltage as yet, will give it a try later. The only thing that stopped 
me thinking that the voltage would make any differenct was that the 
board was getting 1.8v for the core and 3.3v for the peripherals. 

Are you saying it requires 12v for RS232?

Also, what is voltage on your Tx pin on the LPC2106 (at default)?
Regards,

Nick
