1 Introduction
The multiplex mode according to the ETSI TS 101 369, GSM 07.10 Multiplexer Protocol enables one physical
serial interface to be partitioned into three virtual channels. This allows you to take advantage of three simulta-
neous sessions running on one serial interface. For example, you can send or receive data on the first channel,
while the other two channels are free to control the GSM/GPRS engine with AT commands.
In order to properly communicate with the wireless modem, the application needs to support the Multiplexer Pro-
tocol and 3 virtual ports must be installed. For this purpose a Windows 2000/XP multiplexer driver WinMux2k can
be provided. The driver offers basic multiplexer functionality and serves as a reference implementation to aid
developers and system integrators in designing, developing and testing customized multiplexer applications. As
such, it has been tested by Siemens using a variety of applications and platforms, but naturally, even the most
extensive test setup can never be adequate to cover all conceivable configurations.
The Siemens AG does not guarantee any support regarding the integration of the driver into a customer’s appli-
cation. However, the documentation as well as code binaries and source files can be provided and used for fur-
ther development.
This document describes how to install the Windows 2000/XP multiplexer driver WinMux2k in a Windows 2000/
XP based application.Related Documents
