    C.7 high Resets 20x2

    Hi, I am building a circuit where a Picaxe 20x2 sends serial using the sertxd command when one of 16 inputs go low. Everything works, but the chip resets when input C.7 goes high again. Pins C.0 to C.7 and B.0 to B.7 are held high by 4k7 resistors. A switch pulls these pins to earth via a 1k...

I have been trying for about 3 days to get hserin working on a 28x1 at 9600 baud. I tried generating serial using a picaxe 08M, picaxe 18x...
