 I've used it whithout any problem. I'm using the PIP-02 software. Just
specify the "F84" branch to take into account the change in the fuses.

 Maybe the problem is because win98 detects that the DOS software uses the
serial port in a low-level way. In these cases, win98 suggest to use the
DOS mode. Try to use the programmer outside windows, using the "F8" key at
start-up and choosing "only command line".
 However, I have one computer (200MMX) in which it has been imposible to
use the ludipipo programmer, but with others (old 486, P-II 450MHz and
P-100), I've no problem. I don't know the reason.
