#78074 - RE: P89C51RD2 X P89V51RD2
Responding to: ???'s previous message
but I have only start/reset/start/reset ...
Just a wild guess
The V series start up in ISP mode and if nothing happens on the UART for 400ms, they switch to "run program mode".

Again this is a wild guess: if your Rxd wiggles or goes low within those 400ms, something strange COULD happen.
