Lpc2000

I am having no luck with the LPC2000 Flash Utility (V2.2.1) and LPC2138 
chips

I tried with P14 low (although on the LPC2106 this doesn't matter as the 
ISP runs if there is not a valid program in it)
I can see the data going into UART0 but the output remains high impedance.

I then tried programming a chip on my developoment board (via JTAG) to 
call IAP 57(dec) (ReinvokeISP) - still no banana! - and I know that this 
UART circuit works

The date code on the chips is 0501

Anyone got any ideas?
