- On mine, I've got a MIDI port, which has a button to switch between
- MIDI and RS-232 output. When I want to unplug the serial, I switch it
- to MIDI, and the port is isolated from any transient surges. The same
- ought to be true for any switching box. IMHO, it was a bad mistake
- for them not to put line buffers on those ports, rather than running
- them directly to expensive VLSI (but ATARI made the same mistake)
