Notes:
1. The <channel_list> parameter can be a single input/output route connection or a list of
input/output routes separated by commas. Each input/output route is specified by using
the syntax: <input_channel>!<output_channel). (i.e., OPEN(@27!45) or
OPEN(@27!45,36!21)
2. If AUTOupdate is not enabled (default), then connections and disconnections are not
performed until the UPDATe command is received.
3. The OPEN and CLOSE commands may optionally be proceeded by ROUTe:.
4. Lowercase letters in the command are optional.
5. On queries returning a binary status, the following applies: 1 = Enabled, On, Pass, 0 =
Disabled, Off, Fail (*ESR? returns 0 for no error, and other than zero for errors)
