A tri-state general I/O pin on the master.
Output low = reset
Input = do nothing
I can't say. This is all theory for now, but is supported by posts on google and a forum elder,...
But will that work if the slave is caught in a loop or some such?
I'm aiming for a complete reset with no decision from the slave.
This comm scheme sounds like ISO-9141. Been around for years.

What drives the MCLR pin of the slaves? A PIC output?
I am asking, because the MCLR pin needs a level of 0,2*Vdd to see LOW (for the 16F177x series, but I guess it is the same for others).
It...

I ended up with this design, using tri-state pin on master to reset all the slaves when required. This will not be used for programming the slaves, only resets.
