Everything used to work fine, until a little while ago when I accidentally plugged my MIDI interface into my powered-up Amiga. There was a bright spark, and following that the MIDI refused to work. Nothing strange so far. Except that my modem still worked perfectly. A friend of mine said that the MIDI protocol uses a subset of what a modem does as far as RS-232 signals go. So theoretically, shouldn't the modem NOT work if there was any damage the the serial port? I swapped my serial and parallel CIA chips, just to see if one had fried. No dice. Same result. The results remained even after using A) Different MIDI interfaces, B) Different MIDI cables, and C) A different synthesizer. All throughout this, the modem still worked perfectly in the same serial port that the MIDI was flouting. The only further clues I have is that every now and then, for no explanable reason, the MIDI will suddenly come to life for a few seconds, registering input on a MIDI monitor program on the Amiga end. Then, invariably, it will freeze up and cease to work thereafter. Does ANYONE technically inclined have an inkling of what my problem is? I'm at the end of my proverbial rope here. Any EMAIL suggestions would be appreciated with fervor.
