It's a rudimentary software so doesn't have the smarts (API) for COM port settings other than the default COM1 in the old days. Therefore the COM port needs to be set to COM1. So, launch Control Panel->Device Manager->Port(COM & LPT)->USB Serial Device (COM7)->Properties->Port Settings->Advanced settings.

Change it to COM1 in the drop down list of COM Port Number as shown in the pic (COM1 in your case). The OBD.ini should automatically pick up the new COM port value you just set, but, in any case, just verify that it now shows "Port=Com1".

Your EDIABAS.INI settings look good to me.
