I am conceptualizing a project I want to do and I am wondering whether I will be able to update the code remotely via modem?· Thanks.

    The problem you run into here is that the BS2 IDE uses the 'ATN' line (RS-232 DTR, DB-9 Pin 4) from the PC to reset the BS2. Then, the timing between sending a byte from the PC and getting an Acknowledge back from the BS2 is also tight.

    People have written how to make one BS2 program another. With the data presented there, you could program a PIC to handle a reset signal, handle the MODEM communication, and pass data to the attached BS2 for reprogramming.

    I think it will take another PIC of some kind to do it, though.
