1 Introduction
This document describes the application programming interface (API) of the Teridian 73M1x22 Modem
API. The API is defined as a simplified functional interface that allows an application program written in
“C” language to communicate with the driver without going through complicate and cumbersome Linux
®
driver IOCTL. In addition, the API subsystem also encapsulates the asynchronous event notification and
provides a much simpler mechanism to the user application via a callback function.
The API subsystem resides between the user application and the driver layer as shown in Figure 1.
