Is it possible to connect pin ATM (Pin 3 of BS2) through a switch to the ground, so that when the switch is off I can program and when the switch is on I can get the PC and BS2 communicating. (i.e. is it possible to drain away any logical high from ATN to stop reset)

There was already and answer to your issue posted at the following link. Please follow-up in that thread. You definately don't want to just ground the signal or you could damage the PC Serial Port.
