Facility Handling
The ACC X.25 API routines provide a low-level interface to the ACC X.25
subsystem. These low-level routines do not provide any facilities
checking or negotiation. All handling of facilities data must be performed
by the application, including flow control and throughput class
negotiation. Note that the X.25 subsystem will recognize and use the
correct negotiated level 3 window size and packet size parameters.
