Multiplexer Driver Developer’s Guide s 1 Introduction 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

Multiplexer Driver Developer’s Guide s 2.2 Handling of the Physical Serial Port Figure 1 shows the driver architecture of winmux2k.sys in the operating system. The device driver winmux2k.sys emulates virtual serial ports. The lower layer of the WinMux2k driver is the physical serial port driver (serial.sys). The WinMux2k driver is loaded during system startup. It creates virtual port objects. The physical port is opened, when the first virtual port is opened by an application. If the last virt

This means that when you migrate to another module type you are required to uninstall the driver and reinstall it with the new module. The settings are taken from the winmux2k.inf file. The tables below list the commands sent to the module during the initialization. As the init s

Multiplexer Driver Developer’s Guide s 2.7 Module Re-initialization 2.7 Module Re-initialization If the module is disconnected or powered off during normal operation, the driver detects this and tries to reinitial- ize the module. Because the module state can be changed while disconnected the multiplexer mode has to be completely initialized. The driver checks the following situations: • Invalid frames from the module are received. • Timeout occurs during sending frames. • DSR signal goes to ze

Multiplexer Driver Developer’s Guide s 2.8 Power Down 2.8.3 Power Down on PC Shutdown When the PC is shut down, the multiplexer mode is turned off and the strings from the Registry value “ShutDown” are sent to the module, if a virtual port is in use. Note: During shutdown, some PCs may generate an impulse on the lines of the serial interface. In applications where the DTR line connects to the ignition line (IGT), an impulse received on DTR will immediately cause the module to be restarted fro
