<p>In a multiple line adapter organization for a data-comm network, each line adapter providing a receiver-transmitter (USART) (508) and timer (507) means which can interrupt and request service from an associated microprocessor (600). The microprocessor (600) uses Read operators which can then identify the unit requesting service and identify the type of line operations to be used by that particular line adapter.</p> |
