Lets see, modems were never a viable way to locally network two computers. Even a null modem cable between two serial ports was always a better option. Personal opinion has been that internal modems were a bad idea anyway, the blinking lights are too useful and the configuration problems are always more serious than with ones that connect to a serial port. I would just dig up a 56k external serial modem and use that for some form of dial up networking or a serial/parallel cable option for local connections and not worry about the trouble of setting up the bridge from the zorro slots in you A2000 then trying to find some way of driving the ISA modem.
