tamper prevention?

small question??

let's say that i didn't want anyone accessing the stamp (once it is mounted on a circuit and running) could i have a (hidden) jumper sending +5v to the reset pin?

how would this affect the program running asides from not allowing it to download any further info?

how could i put a "lock" on the program?

thanks

i looked but i didn't find a link related to this.

    It would not be a good idea to tie the·RESET line to 5V.· That line is internally pulled high.· Instead perhaps you should disconnected the DTR/ATN line from going to the Stamp Module.
