Hi Alain.
All good! Thanks for your concern. Hope and wish for you too.
Well, pescador said that with the (strange) load he places on the output, the PIC seems to reset. So, that is why I asked for an oscilloscope to see what actually the PIC does on that pin while trying to change the state. It may reveal more that way, for example:
1. Previous state
2. New state
3. How long the new state is output
4. Is it overloaded as initially was suspected?
5. Is it tristated?
