•Start the Bluetooth connection using the driver provided by the USB Bluetooth dongle.

•Through "ComBridge", one virtual COM port supplied by "WinMux" is connected to the SAP COM port of "PlugFree". This establishes a direct communication link between the cellular engine and the cellular phone. However, take into account that AT commands can still be entered on the remaining multiplexer channels of the ME.

•Select the "ComBridge" SAP filter.

•Press the "ComBridge-Start" button to connect both MEs.

•Start the SAP client using the AT command "AT^SRSA=2,2,3,1", if multiplexer channel 3 is used.

15.3.3Serial Interface Scenario (XSAP)

This example describes the connection of two cellular engines. It is recommended that the instructions be fol- lowed in the order that they are presented:

•Install two WinMux drivers on the PC and connect each ME to the physical port of a Multiplexer.

•Connect the PC application "ComBridge" to one virtual COM port of each Multiplexer. This establishes a com- munication link between the two cellular engines. Bear in mind that AT commands can still be issued on both cellular engines using the remaining serial channels.

•Select the "ComBridge" XSAP filter.

•Open the XSAP "Config Filter" menu and deactivate the "Startup - Send Initialization" and the "Shutdown - Switch back to local SIM" tags. However, the appropriate device IDs need to be entered in the "Startup" frame.

•Press the "ComBridge - start" button to connect both MEs.

•Start the SAP client via AT command "AT^SRSA=2,2,3,0", if multiplexer channel 3 is used.

•Start the SAP server via AT command "AT^SRSA=1,1,3,0", if multiplexer channel 3 is used.
