Token – A term used with the LAN to describe a special LAN message. This
message is passed from one LAN Node to another. When a LAN Node receives
this message (i.e. the token), it is allowed to transmit a message it has generated
while waiting to receive permission to transmit. Once it has completed its
transmission, it must pass the token to the next node (in numerical sequence).
Nodes which do not have the token may receive messages but may not transmit
a message until the token is received. If the node receiving the token does not
have any messages to transmit, it simply passes the token to the next node.
