Hi, I'm testing a PIC by sending data to it's RX with a terminal (teraterm), the PIC works on the data and outputs the result to the TX, which I receive and read in a second Terminal. I find that when the power is switched off, for PIC removal and re-programming or resetting, the terminal holds the PIC on via the TX and RX pins. I tried a 0.1uF capacitor in series with the RX TX connections and this appeared to solve the power problem, and seemed to work regarding the terminal. Is this an acceptable way to work? Camerart.
