Working with ZET 7070 as COM port
To connect ZET 7070 to OS Linux, it’s necessary to configure its VID and PID. For example, you can do it in Ubuntu 14.04 LTS using the following command (with administrator’s rights): echo 10e8 3820 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id. After running this command, connect ZET 7070 to a USB port on a Linux PC: a device with number /dev/ttyUSB0 (or other number, e.g. /dev/ttyUSB2). You can use the dmesg command to check the connection.
