ASC Software Overview

asynchronous connection capabilities by using the OpenView DTC

Manager workstation instead of the host. This prevents you from

having to reconﬁgure your HP 3000 Series 900 computer.

NOTE

The concept of nailed and non-nailed devices deals only with the

association of a device to an ldev number on a speciﬁc MPE/iX system.

It is independent of the concept of switching, which deals with the

ability of a single device to establish a connection to any of several

MPE/iX systems on the LAN.

A terminal connected through a DTC on a LAN with multiple MPE/iX

or UNIX systems may be conﬁgured as a nailed device on more than

one host system. Alternatively, it may be nailed on one host system and

not nailed on another, or it may be conﬁgured as a non-nailed device on

all the systems to which it has access.

For more information on conﬁguration of asynchronous devices on

networks managed by an OpenView network management workstation

Systems for Terminals, Printers, and Other Serial Devices.
