DOS BASED APPLICATION SUPPORTS FOR A CONTROLLERLESS MODEM |
摘要 |
DOS application programs are accommodated when using a controllerless modem by providing a virtual device driver. The virtual device driver emulates UART to UART communications and handles interrupts by the DOS applications and by a hardware port managed by the controllerless modem. In one implementation, the virtual device driver shares a communications interface in common with 32-bit applications. In a communication system environment, DOS applications can participate in modem to modem communications with remote DTEs and with other devices using the services of the virtual device driver.
