Look in the User Manual for the processor of interest.  I wrote my IAP / 
ISP programming utility from the info in the LPC2138 User Manual.  You 
have to tinker with it a bit to see what is the manual is telling you, 
it is not quite intuitive (e.g. it does pass you back ascii chars, not 
binary data bytes).
