Troubleshooting Terminal, Printer and Serial Device Connections - Edition 4 (32022-90030)

Preface

This manual documents functionality for the MPE/iX release for

HP 3000 Series 900.

This manual is designed to aid the troubleshooting of device

connections. Information and strategies for troubleshooting networking

environments is provided. TermDSM is a utility program used to

troubleshoot:

• Terminal connections.

• Printer connections.

• Other serial device connections.

This manual only covers troubleshooting connections for host-based

management (i.e., when the DTCs are managed from an HP 3000 host).

For troubleshooting on PC-management (when DTCs are managed by

an OpenView Workstation), refer to Using HP OpenView DTC

Manager.

NOTE MPE/iX, Multiprogramming Executive with Integrated POSIX, is the

latest in a series of forward-compatible operating systems for the

HP 3000 line of computers.

In HP documentation and in talking with HP 3000 users, you will

encounter references to MPE XL, the direct predecessor of MPE/iX.

MPE/iX is a superset of MPE XL. All programs written for MPE XL will

run without change under MPE/iX. You can continue to use MPE XL

system documentation, although it may not refer to features added to

the operating system to support POSIX (for example, hierarchical

directories).

Finally, you may encounter references to MPE V, which is the operating

system for HP 3000s, not based on the PA-RISC architecture. MPE V

software can be run on the PA-RISC HP 3000s (Series 900) in what is

known as compatibility mode.

Skills

Troubleshooting Terminal, Printer, and Serial Device Connections will

be of greatest value to the person responsible for the overall operation

and reliability of an MPE/iX computer. This person is usually called the

system administrator or system manager, and needs to be able to

prepare devices for operation and to conﬁgure the computer to

recognize asynchronous devices.
