  1. The sock.allowedinterfaces property refers to the Ethernet interface as "NET," PPP as "PPP," and PPPoE as "PPPOE." The sock.targetinterface and sock.currentinterface properties rely on the pl_sock_interfaces enum, whose members differ depending on the platform.
  2. Surrounding board hardware dictates which GPIO lines must be used as inputs and which as outputs.
  3. The hardware of this platform supports serial channels, which means that CTS/RTS and DTR/DSR pairs of the DB9 connector can also be used as RX/TX pairs of additional serial channels. Therefore, it is up to you to decide which lines are used as RTS and CTS, and which channels they will belong to. Proper mapping will be required to implement each particular arrangement.
  4. Older DS1206 devices did not contain the serial number. To find out if your DS1206 has the serial number onboard, try to read it with the sys.serialnum R/O property. If this property returns an empty string, then the serial number is not present, otherwise it should return all 128 bytes of the serial number. The first 64 bytes are one-time-programmable (OTP) with the sys.setserialnum method.
