About This Document
Overview
Introduction
In This Section
The 68K Monitor is a feature of all GE Energy Services products that use a variant
of the Motorola 68000 series of microprocessor.
Since the introduction of the first D20 products, the commands that are available in
the 68K Monitor have changed, been added to, and enhanced to address the
requirements of the newer products and their software components.
This guide summarizes all of the commands that you will find in any of GE Energy
Services’ products to-date. You will see in the next chapters that not all commands
are available in all products. Some commands exist only for product and software
development, and are not found in end-user products.

What This
Document
Provides
While only experienced programmers should use many of the commands found in
this guide, maintenance technicians and other support personnel will also find this
guide useful.
GE Energy Services’ customers and employees who wish to view detailed
information about the software and hardware should use this guide.
This document assumes that you are familiar with software and programming
terminology and practices, and have some knowledge of both the hardware and
software.
This guide covers the commands found in the 68K Monitors that run on these
platforms:
• CPM running CPM Base
• D20 running D20 Base software
• D20 with D20 ME running D20 Base software
• D20 and D200 using CCU Base software
• D20 and D200 with D20 ME processors running CCU Base
• D25
Notes will show where a command or feature is unique to a specific platform.

WARNING
What This
Document Does
Not Provide.
Document Style
and Convention
Rules
This guide is a user reference for the 68K Monitor. It describes in detail the contents
and usage for each available user command. These commands are useful for testing
and debugging hardware and software as they provide a means for controlling the
system environment at a very low level.
The functions provided by 68K Monitors enable you to alter and manipulate the
system at a very low level. At this low level, it is easy to seriously disrupt an
operational system.
You must be aware of this possibility at all times.
There are no procedures in this document as users should already be familiar with
accessing and using GE Energy Services’ WESMAINT and monitor maintenance
facilities.
This manual uses the Systeme International (SI) and the Microsoft Manual of Style as
a basis for styles and conventions.

Chapter 1: Connecting and Using the 68K
Monitor
Overview
Connect Defined
In This Chapter
An application interface provides an input to and output from the 68K Monitor.
This allows the 68K Monitor to ‘connect’ to any application or subsystem, and to
any type of hardware (capable of stream or block transfers).
As examples:
• WESMAINT or the Login Process can connect the 68K Monitor to a serial port.
• WESMAINT and the TELNET application can connect it to the TELNET
session.
The 68K Monitor can also be ‘connected’ to a file system to receive (read)
commands from a file and send (write) responses to another file.

Prompts
Examples
While any application running in the system can activate the 68K Monitor, only one
instance of the monitor can be active at any one time.
If a second application attempts to start the 68K Monitor, it will refuse the second
application’s request.
The prompt produced by the 68K Monitor depends on the hardware platform and
the mode the device is in.
As examples:
The table below shows examples of the prompts that you may see on various devices
in different modes of operation.

D20M(++)
The 68K Monitor will detect a loss of connection in a TELNET session and will end
the monitor session, allowing a new connection to be established.
The 68K Monitor itself never terminates or initiates a TELNET session. Whatever
process starts the 68K Monitor handles this functionality.
Since only one 68K Monitor session is allowed at a time, it automatically terminates
a session if no input is received for 5 minutes (default) or after a user-programmed
interval.
Refer to: Page 3-4, AL - Change Auto-logout Timer for details about how this timer
can be changed.

Format
Common
Command
Syntax
Input to the 68K Monitor is read from the ‘connected’ application / subsystem. The
input takes the form of user-entered commands.
The 68K Monitor accepts a command line:
• that is no longer than 80 characters, and
• consists of no more than 16 separate words or symbols.
− The definition of a word or string is one or more characters separated by one
or more spaces.
− Input may be either upper or lower case, except where noted.
Input may be either upper- or lower-case.
The format of all commands is as follows:
<command_name> < parameters arguments>
Where:
• command_name is one of the recognized commands, and
• parameter arguments are an optional list of command parameters.
You must format these commands in a definite way or syntax. You must understand
command syntax to understand detailed command descriptions in the following
chapters.
List of

This tables lists some of the characters used in command syntax:

ESC deletes all current data on the command line and returns to the first

ENTER executes any command that has been entered on the command line.
BACKSPACE removes the last character from the end of the current command
line and moves the cursor one character position to the left.

Command Characters Description
Abort CTRL-C returns the Monitor to the command line prompt
and aborts most commands being processed.
Note: a
CTRL-C command does not work in
a TELNET connection.
Delete CTRL-D deletes the current character of the previous
command line.
Insert CTRL-I or
TAB
toggles the current mode to/from overwrite or
insert. The monitor always starts in overwrite
mode.
Advance CTRL-A causes the monitor to copy the character from
the previous command buffer reference location
to the current location in the input command
buffer.
This character also returns the monitor to
overwrite mode.
Repeat CTRL-R allows editing and re-execution of the previous
command by copying the previous command
line from the character at the previous
command reference location (up to the end of
the previous command buffer) into the current
input command buffer
Note: D20ME and D25 have a 5-line
command buffer.
Execute CTRL-X copies the most previously used command to
the command line and executes it.
Xoff, Xon CTRL-S
and CTRL-Q
the combination of CTRL-S (Xoff) and CTRL-Q
(Xon) stops and starts scrolling of the monitor’s

68K System Monitor
User's Guide
Output from the
68K Monitor
Display Output
An Example:
The 68K Monitor’s output is a stream of ASCII characters written back to the
‘connected’ application / subsystem. The command executed determines the exact
contents of the output.
When encountering a system exception error, or a defined breakpoint, exception and
breakpoint handling routines will generate additional output.
While most output to the monitor port is a direct result of command input, some
occurs asynchronously of the command input.
This requires the use of two methods of output display.
• The first method uses the monitor-input process, which formats the output into
a common buffer and signals the output process that data is available.
− All output that occurs synchronously with the input uses this method,
including command data and input line display.
• The second method uses exception-handling routines to display data that may
or may not occur as the result of a monitor command, but cannot be expected to
occur synchronously with the input.
− A pSOS exchange sends this data (including unassigned exception and
breakpoint data displays) to the output process.
Once a breakpoint is set, the monitor cannot control when or if the system encounters
the breakpoint.
The exception and breakpoint display output may occur at any time, and this output
has priority over monitor input process output. This may cause occasional
interruption of a command or input in progress, or the lack of a prompt re-appearing
after displaying the data, but does not affect these functions in any way

Breakpoint Commands
GE Energy Services
Description
List of
Commands
Use these commands with the 68K Monitor for control and display of process
breakpoints in the system.
The three restrictions with the definition of breakpoints are:
• You must define breakpoints in code that is in RAM.
− The program instruction changes to a 68000 family TRAP instruction.
• You must define all program breakpoints at the beginning of an instruction.
• Only define breakpoints in a process.
− If the interrupt mask is non-zero when you enter the breakpoint handler, the
assumption is that the calling routine is an interrupt service procedure (ISP)
and breakpoints are not valid.
Note: Diagnostic Commands are suspended in order to use breakpoints.
