Updating this issue, I retried the test with another PIC16F84A and I=20 could program it with the blink-a-led example hex from Wouter=B4s site=20 using Xwisp. It looks like the other 84A was defective. I have not=20 tested again with the 16LF648A because I have not built the dongle. I=20 still cant read back the hex from the 84A, I keep getting weird=20 messages. At least I can now flash and test some stuff! Thank you all=20 for your kind help.
