The node-number is the number of the node at which the specified
terminal is located. The line-number on non-network systems is
equivalent to the terminal number. On a network system, line-number
is the physical line number of the terminal on the node to which the
terminal is connected.
Networked terminals are assigned logical line numbers from a pool of
network terminal numbers when they connect to a host. Therefore, the
logical line number will change as the particu'lar node to which the
terminal is attached comes on-line, and as the terminal connects to,
and disconnects from a host.
