I'm using the MIDI port to communicate with a network (only 2 so far) of microprocessors (Intel 8031) using RS485 protocol. This is a two-wire-plus- ground differential line setup using half-duplex mode (ie, the same bus is used for bidirectional data, hence only one party can transmit at a time). The circuit for the level translator is available if anyone wants it. John Purbrick jpexg@ai.mit.edu
