The easiest way would be to wait for an ATN signal from either bus at startup, then servicing only that bus until the AVR is reset. This scheme might switch to the wrong port if there are other devices connected on both ports and not all of them are powered on. A bit less easy to implement is to allow switching whenever the currently-serviced bus is idle and there are no open files. The last condition avoids situations where someone might shoot themselves in the foot, e.g. by accidentally accessing files on the same secondary number from both computers at the same time. I know what is probably the hardest way, but I won't mention it because there is a chance that someone misremembers it and later asks why it wasn't implemented. =) -ik Message was sent through the cbm-hackers mailing listReceived on 2011-06-20 10:00:08
