  • Page 7: Port Mapping

    N720 User Manual (Linux) 1 Port Mapping N720 supports network share via pppd, RNDIS, ECM, and RMNET. Each mode corresponds to different VID and PID. Developers can switch the mode by sending AT command (AT+NETSHAREMODE). The mapping between the ports and share modes is shown as follows: VID: 0x2949 PID: 0x8241 Support pppd/RNDIS dialup ...

    In the figure above, the VID of N720 is 0x2949 and the PID of N720 is 0x8241. If the host does not identify N720, check whether N720 is connected to the host, whether it is powered up and started, or whether it is connected to the host through USB.

  • Page 9: Testing At Commands

    Power up the host again and execute ls /dev/ttyUSB*. If N720 is loaded successfully, ttyUSB0 to ttyUSBx are listed under /dev. Two ttyUSB ports can be used to send AT commands. One is used as modem port and the other one is used as AT port.
