<p>Data-communications unit suitable for asynchronous serial data transmission between a data-processing device and a peripheral device, such as a modem, having, for one or either transmission direction, at least one First-In, First-Out memory (FIFO) for data and for management data, with a view to transmitting and indicating the status of the peripheral device. The FIFO or FIFOs associated with a transmission direction are controlled in such a manner that a sequence of data received by the data-communications unit (irrespective of the type) is maintained at the output side thereof.</p> |
