Hi Bruce and others
Sorry i have to come back to this topic again
On my data logger i simply test RCIF on occasion to determine if the PC has been connected, this works ok
But the problem is that the pic is aspleep 99% of the time and it dosen't responds to the ping when in sleep mode.
i was going to use a link jumper to link a pin to gnd when the user needs to make configurations so that the pic test to see if this pin is 0v than jump over the sleep part of my code but the end user want everything done from the PC end
is there a way i can do even if i have to use more than 3 wires for my serial connection


Regards
Toni
