1. please use DRVTST1.EXE to verify that your programmer
hardware works ok. DRVTST1 is very simple and stupid program,
but you can use it to set or test all the the programmer pins.
>From drvtst1 prompt:
Set data pin to high level ->DATA 1<enter>
read back data pin ->DATA<enter>
should get 1 high level
Set data pin to low level ->DATA 0<enter>
read back data pin ->DATA<enter>
should get 0 low level
if the above sequence works then PIP readback should also work.
if the above fails please check the PICLIST mailings about
comments on data readback hardware issues.
if the problems still exist, let us know.
