Counters - a block of counter information as defined for the
particular data link (see Appendix
B).
Function:
Reserves the,remote system console for use
by this system. This
must be done before the console carrier can be used. The remote
console stays reserved as long as this system makes any console
request before the remote system's reservation timer expires.
If
the remote console reservation timer expiresl this system's
console reservation is lost without notification.
Reservation of a remote console allocates and initializes a
collection of local resourcesl known as a port. Those console
functions,that require a reservation are requested via the port
identification. Initialization of the port allows the command
node to synchronize the command and response data streams with the
target node's Console Server.
In cases where a remote system console can be accessed over more
than one communication channell
it is the responsibility of that
system and the user of the remote console to ensure that there are
no conflicts of control.

honor the request.
outputs:

assign a port for remote console requests.
