ROUTe:CLOSe <clist>
This command functions the same as the front panel CLOSE key (SINGLE menu

specified in the <clist>.
Trying to close an invalid channel (such as a non-measurement channel) with this
command will result in error -222 (Parameter data out of range).

ROUTe:CLOSe:STATe? <clist>
This query returns a "0" (open) or "1" (closed) for every measurement channel
specified in the <clist>. For example, assume <clist> = (@101, 104, 107, 102).
The response message "0, 0, 1, 0" indicates that channel 107 is closed.
The state of non-measurement channels cannot be checked with this command.
