  • Expandable communication system using data concentration
    Patent number: 5280586
    Abstract: A communication system including one or more host adapters connected to a host computer, each adapter having multiple serial communication ports for transferring data between the computer and several TTY devices. Several of the adapter's serial ports include a high speed serial link for communicating with a data concentrator. The adapter automatically detects the presence of a concentrator connected to a switchable port and switches to the high speed link. Each concentrator includes multiple serial ports for communicating with TTY devices, and a high speed serial link for communicating with the adapter's high speed link. The concentrators allow more than one TTY device to share a single adapter serial port. Data from all of the TTY devices is accumulated into an adapter data buffer during a configurable time period or until a certain amount of data is accumulated, at which time the adapter interrupts the computer and transfers the accumulated data to the computer in one transfer operation.
    Type: Grant
