In fact, I tried it at various freqs (40MHz, 20MHz, 10MHz and 5MHz) using=

signal generator and a 40MHz oscilator.=0D

I watched the PORTD pins with an osciloscope. They were all zero.=0D

I just don't understand why it happens, since I've just downloaded an old
program I made to control a LCD and it worked in the same prototype board=

Mmmm I think that that issue doesn't apply for the 18F452, anyway, try=0D
to put a 4MHz cristal and you'll see. On the other hand, how are you=0D
checking that the PIC doesn=92t do anything?=0D
 =0D
In my opinion, it should be working.=0D
