Description (see command description format info here)
nnn.nnn.nnn.nnn.nnn.nnn- MAC-address of the DS;
ppppp- fixed at "65535";
m- fixed to 'L' (means that the NetLoader, not the application firmware is running).
The primary use of the Echo command is to auto-discover Device Servers on the network and to verify that the NetLoader is running. When the network host sends this command in the broadcast mode, it collects the replies from all locally attached Device Servers (hence, the name of the command). Reply from each DS contains all necessary information (MAC-address, etc.) that is needed to continue communicating with each specific DS in a non-broadcast mode. This command has its counterpart in the application firmware (see Echo (X) command).
Information returned by the Echo command contains the following data:
* This is because each DS, like any other Ethernet device, has a unique MAC-address preset during the production.
