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.
