Here is some info for ethernet and RS232 interface control of the 886.
Once you have connected an ethernet cable to your 886 and you know the network (IP) address that your DHCP server assigned the 886, or you assigned manually through the hardware setup menu, you put that IP into your browser's address line and open an HTML interface page onboard the 886.
HERE is an .xls document with all of the control codes listed for the various modes. You'll need to have a MS Office compatible spreadsheet reader installed to view it. Enjoy!
