Note: if you are NOT using VirtualBox, then you may skip step 1.
- Map the COM Port of Modem (COM3 in this tutorial) to COM1 (or any COM port n umber) in VirtualBox. If this step is missed, then MOBITEK S80 will not response in CuteCom or Putty (terminal).
- To check if MOBITEK S80 is connected to the USB port, type “lusb”. It will show MOBITEK S80 Modem as “Sierra Wireless, Inc. MC8700 Modem”.
- But in this VirtualBox (virtual machine), MOBITEK S80 is connected under “Serial Ports” (as per step 1) and not under “USB” of the VirtualBox. To check which serial port is MOBITEK S80 Modem connected, type in “dmesg | grep tty”. In this example, it shows “ttyS0” which is COM1 that was set in step 1 above.
- Run CuteCom. Select “/dev/ttyS0” in device and click Open device. Then type the AT command.
