Method 2: Using AT-commands via RS232
It is also possible to configure the Ethernet box by sending modem (AT-)commands via RS232. You can send
these commands manually via an RS232 monitor (i.e. Hyperterminal or Appload) or for a quicker setup you can
also connect an (RS232) barcode reader and scan configuration barcodes.
The following AT-commands can be send to configure the Ethernet box.
