Responses to Code Control commands are optional and set via the Programming
menu.
4.4 Lead Control of Ports
The Remote Management Switch can automatically select ports via control leads.
You must set up this feature before using the Switch. Any port can access the
master by raising the RTS or DTR lead (jumper selectable) provided no other port
is already connected by Menu, Manual, or Code Control. If another port is
connected, the request is placed in queue. The queue is first-in, first-out.
Once a port has been connected via lead control, it remains connected until the
control lead has gone low. If a port has been manually selected, and another port
requests access, the manually selected port remains active until it is deselected via
Menu, Code, or Manual Control.
