An i/o handler (10) providing communication between a host computer (12) and a plurality of pheripheral stations (14-22) has an abutting member (28) positioned adjacent to the computer (12) and a distributing member (30) removed from the computer (12). The two members (28, 30) are connected by a communication link (32) with data paths (30, 38) and separate control paths (36, 40, 42, 44). Communication on the link are by a protocol with synchronized time multiplexed channels and exchange of synchronizing signals in every frame. The handler (10) minimizes the space required at the immediate site of the computer of external communications. |
