ABSTRACT:
A host data processing system which includes a plurality of input/output devices operates under the control of an enhanced version of the UNIX operating system. The host system includes an emulator which runs as an application process for executing user emulated system (ES) application programs. The emulator includes a number of emulated system executive service components operating in shared memory and an interpreter, an emulator monitor call unit (EMCU) and a network terminal driver (NTD) component operating in the host memory. Configuration command means are provided for initially configuring a host terminal to operate in a plurality of asynchronous driver (ATD) modes implemented by the NTD component. When a terminal has been configured by a user to run applications written for the ATD driver, it sets a mode indication which causes the NTD component to respond to user applications as an ATD driver and determine if each ATD request can be carried out with functionality included within the NTD component. If the request can be carrier out, the NTD component translates ATD device specific information contained in each request into NTD device specific information which invokes the required functionality at the appropriate time so that the request can be processed by the NTD component. At the completion of each such request, the NTD component utilizing information contained in the original request updates the return status information to that of the ATD driver. This arrangement provides ATD applications access to NTD controlled host terminals without having to port ATD software or have users modify their existing applications.
