CLOSe?
[ROUTe:] CLOSe? <channel_list>
returns the current state of the
channel(s) queried. channel_list has the form (@ccnn) (see
[ROUTe:]CLOSe for definition). The command returns 1 if channel(s) are
closed or returns 0 if channel(s) are open.

Query is Software Readback: The [ROUTe:]CLOSe? command
returns the current software state of the channel(s) specified. It does
not account for relay hardware failures. A maximum of 127 channels
at a time can be queried for a multi-module switchbox.
Example
Query Channel Closure:
This example closes channels 100 and 213 of a two-module switchbox and
queries channel closure. Since the channels are programmed to be closed 1,1
is returned as a string.
CLOS (@100,213)
Close channels l00 and 2l3
CLOS? (@100,213)
Query channels l00 and 2l3 state
OPEN
[ROUTe:]OPEN <channel_list>
opens the Form C Switch channels
specified by channel_list. channel_list has the form (@ccnn) where cc =
card number (01-99) and nn = channel number (00-15).

Opening Channels: To open a single channel, use [ROUTe:]OPEN
(@ccnn); for multiple channels use [ROUTe:]OPEN (@ccnn,ccnn,);
for sequential channels, use [ROUTe:]OPEN (@ccnn:ccnn); for
groups of sequential channels, use [ROUTe:]OPEN
(@ccnn:ccnn,ccnn:ccnn); or any combination. Opening order for
multiple channels with a single command is not guaranteed.

*RST Condition: All channels open.
Example
Opening Channels:
This example opens channels 100 and 213 of a two-module switchbox (card
numbers 01 and 02).
OPEN (@100,213)
Open channels 100 and 213. 100
opens channel 00 of #1 and 213
opens channel 13 of card #2.
