Host-based DTC management
There are certain features of DTC configuration which could not be accomplished from
the host-based configuration interface; perhaps the most popular of these capabilities is
the ability to allow a port to "switch" or select different hosts to connect to.
(DTCs can connect to HP3000s using AFCP [and other] low level protocols, as well as via
telnet to any host that accepts inbound telnet connections.)
As of MPE/iX 5.5, the host-based configuration facility has been greatly enhanced,
making much of the configuration process much easier (and may support switchable ports?)
