2.6Module Initializing Sequence

Due to different requirements of the supported products the initialization sequence varies with the module type. 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 string information is stored in the Windows Registry the corresponding values are also listed. For further details on the Registry see Section 4.2.

Table 4: Module initialization of supported modules

Command	Response	Function	Associated Registry
			value

AT	OK	Detection of connected module.

AT+IPR=115200	OK	Baud rate specified in the Windows	“BaudRateString”
		Registry during WinMux2k installation.
		The value may be different according to
		individual settings.

AT	OK	Check if change of baud rate was suc-	“ModemInit”
		cessful.

AT&S0\Q3	OK	Sets DSR always on and hardware flow	“ModemInit”
		control. The settings are read from the
		Windows Registry.

AT+ICF=3	OK/ERROR	Sets interface mode 8N1. This com-	“ModemInit”
		mand works only on modules support-
		ing different interface modes (TC35i,
		TC63, TC65, MC75, AC75). The set-
		tings are read from the Windows Regis-
		try.
		The resulting ERROR on modules with-
		out support of the AT+ICF command is
		ignored by the WinMux2k driver.

AT+CMUX=0	OK	Switches to multiplexer mode. This	“ModemInit”
		sequence is read from the Windows
		Registry. More AT commands can be
		sent to the module at this point.

Note: The initialization sequence overrides the user profile settings defined with AT&W on channel 1 for the com- mands AT&S, AT\Qn and AT+ICF. After restart without multiplexer, the user profile will be loaded with all your individual settings.
