Example:
OP 7.3-151
This OPEN command will open all of the channels between 003
and 151 of the module at switch card module address 7.
Example:
OP 7.110-120,122-144
This OPEN command will open all channels between 110 and 144,
except channel 121.
The EXCL command is used to define an "exclude group". Two or
more relays may be defined on a single exclude group. Multiple
exclude groups may be defined.
Relays in an exclude group are considered mutually exclusive from
each other. When a relay in an exclude group is closed, all other
relays in the same exclude group are opened.
The EXCL command uses the syntax:
EXCL <exclude list> [E; <exclude list> ]
where:
<exclude list> is a list of two or more relay descriptors.
The relays do NOT have to be on the same 1260 module, nor do
