Keystrokes
The keyboard commands on these menus are usually not case sensitive. You
can enter most commands in lowercase or uppercase letters.
The menus use a few special characters ([?],
[-],
[+],
[@]) that must be entered
exactly as shown. Some of these characters require you to use the [SHIFT],
[CTRL], or [ALT]
keys to enter them correctly. For example, on US English
keyboards, enter the [?]
command as [SHIFT]
and [/].
Also, take care to distinguish the capital letter [I] from the lower case letter [L] (l)
and the number [1]. Likewise for the capital letter [O] and the number [0].
Although these characters look nearly the same on the screen, they perform
different actions on the module.
4.2.2 Main Menu
When you first connect to the module from your computer, your terminal screen
will be blank. To activate the main menu, press the [?]
key on your computer’s
keyboard. If the module is connected properly, the following menu will appear.
Caution: Some of the commands available to you from this menu are designed for advanced
debugging and system testing only, and can cause the module to stop communicating with the
processor or with other devices, resulting in potential data loss or other failures. Use these
commands only if you fully understand their potential effects, or if you are specifically directed to do
so by ProSoft Technology Technical Support staff.
Some of these command keys are not listed on the menu, but are active nevertheless. Please be
careful when pressing keys so that you do not accidentally execute an unwanted command.
Opening the Data Analyzer Menu
Press [A]
to open the Data Analyzer Menu. Use this command to view all bytes
of data transferred on each port. Both the transmitted and received data bytes
are displayed. Refer to Data Analyzer (page 59) for more information about this
menu.
