As an alternative to specifying the directory distinguished name, you can
specify the P_address when invoking ft_connect() to communicate with
other systems and processes.
The P_address must be unique within the network and must be exactly
the same as the one set during configuration. To have the system
automatically set the P_address structure, call convert_paddr; the source
is in /opt/ftam/demos/cnvrt_addr.c.
• Each application on a node must have a unique triple of p_selector,
s_selector, and t_selector. For example, one application could have
(0000,0000,0000), another (0000,0000,0001), and another
(2375,232323,75757575).
• Each node must have a unique nsap.
• The maximum length of the P_address is 224 Octets. These Octets
can be printable or unprintable characters.
• Each called_dir_name has a corresponding P_address. Directory
Services provides the mapping between the two.
