ABSTRACT:
An interface between a bus-oriented computer and a packet-based serial link. A block of data is transferred from the serial link to a buffer, whereupon the bus is issued a request for service. When the bus has read the buffer, the serial link carries an acknowledgement of the reading. If the buffer has not been read, no further block of data is transferred into it. The bus also writes a block of data into another buffer from which it is sent over the serial link if the previous such block has been acknowledged.
