Abstract
A modem is implemented as a virtual device driver with all processing handled by the host computer thus obviating the need for a stand alone processor for the modem. The modem virtual device driver ensures that the modem obtains adequate processing time regardless of other processes running on the host. By combining a port driver directly into the modem contact code, the need for a hardware UART with its attendant limitations is eliminated.
