Description
Data type: Integer
Access: No limitations
The state of the channel - whether it is in
use or not. When a channel is not in use,
no data can be transmitted on it, and no
data is received from it. The channel
attributes can be read as usual. Generally,
a channel must be taken out of use by
setting this attribute to 0 before the chan-
nel attributes can be written.
When a channel is stopped by setting the
In use attribute to 0, all data transmission
on the channel ceases. However, before
that, the protocol stack executes to the
end all on-going data transactions. For
example, the polling of the station in turn
is completed.
