DNS. Register 0xD3 stores the address length of preferred DNS, and 0xD4 to 0xDD stores the address ASCII code value of preferred
DNS. Register 0XDE stores the length of the standby DNS address, and from 0XDE to 0XE8 stores the ASCII code value of the
address of the standby DNS.
The preferred DNS and standby DNS can be configured with 10 function codes at one time. The table below shows the configuration
preferred and alternate DNS are 61.139.2.69 and 192.168.4.1 respectively.
