Return Format
The query command returns the Default Gateway address in the form
"nnn.nnn.nnn.nnn".
Note that the query command has two optional parameters. Specify
"CURRent" (default) to read the dynamic Default Gateway currently being
used by the instrument. Specify "STATic" to read the Default Gateway
currently stored in non-volatile memory within the instrument (may not be
the actual address used by the instrument if DHCP is enabled).
