Ooops,
My book 'PIC cookbook for virtual Instrumentation'
Project 'digital Thermometer 'schematic has an error .The crystal frequency should be 6 Mhz, not 4.1943 Mhz.
The journey from prototype version 1...version 6 to the published article is a long one and mistakes can arise especially after I have been to the pub.
I found the error after I built the project according to the Book and then found the error.
Sorry about that,
Richard

When using an industry standard 'prolific' RS232/USB convertor (price 10-15 pounds) an easy way to replace this bridge is to use FTDI's ic (FT232Rx,cost 3 pounds) and use a single gate invertor i.c. between the PIC output and the RX pin of the FT232Rx). and use the same RS232 PIC software.
Better than changing the RS232 PIC software by inverting.
