Appendix B UCD-XL Utilities
There are four utility programs that enable the UNIX system administrator to 
access the shared memory and semaphore set utilized by the components of UCD-
XL. These programs are located in directory /oai/app/ucdxl and may be run from 
the UNIX command line. 
Note:
Upon initialization, the Monitor clears shared memory and the semaphore set, 
creating them if necessary.

This utility checks the set of two semaphores utilized by UCD-XL on a periodic 
basis. The first semaphore is a flag that prevents more than one UCD-XL 
component from modifying shared memory simultaneously: 1 = unlocked, 0 = 
locked. The second semaphore is equivalent to a count of outstanding requests. 
Every Messenger waits for this semaphore to become non-zero, then takes its turn 
reading the next outstanding request in...

Appendix C UCD-XL Environment and Hardware
This appendix describes the physical environment and hardware needed to support 
UCD-XL.
A Digiboard DigiCHANNEL, NEC Multi-8/16, or similar serial 
communications board is required in the UAP to supply sufficient ports for the 
MCI links among the PBX, the VMS, and UAP (UCD-XL). RS232 cables 
comprise the links. Connectors may be DB-25 (25 pins) or RJ-45 (8 pins)...

The NEC Multi-8 and Multi-16 Boards are DTE devices that use RJ-45 
connectors. The signals are laid out on a Multi-8/16 RJ-45 connector as follows:
The MCI link between A/B box #1 (the PBX side) and the NEC Multi-8/16 
Board on the UAP requires an adapter that connects DTE (Multi-8/16) to DCE 
(PBX). This wiring configuration is as follows:

The Digiboard DigiCHANNEL serial communications board is a DTE device 
that uses either RJ-45 or DB-25 connectors. The pin assignments for both types 
are given below:
For the connection between A/B box #1 (PBX side) and the DigiCHANNEL on 
the UAP, there is no special wiring unless an RJ-45/DB-25 adapter is needed. In 
that case, the signals are maintained by wiring together the RJ-45 and DB-25 
pins for each...

For the connection between A/B box #2 (VMS side) and the DigiCHANNEL 
on the UAP, the following wiring configuration is needed to form a DTE-DTE 
connection:
