disabling programmability of Stamp

NeilB

Hi,
I have an application that requires the use of the built in serial port on a BS2p40 for serial communications with a PC. I would like to be able to enable/disable the ability to program the Stamp through that port, by means of a mechanical interface (switch, push button, etc.) In other words, I want to only allow the Stamp to be reprogrammed when a switch is thrown or a button is held down, and I need it to act like a regular old serial port the rest of the time.

Any suggestions?

Neil

If you break the connection to the ATN pin (pin 3 of the BS2 module) you will disable programming.
