To enter the fullscreen mode, at the command line prompt (>), type in the
commands:
>SET LT OFF
>SET FS ON
The SET LT OFF command disables the LAPD timeout. If the TRU detects
loss of the LAPD link, it resets itself after 10-12 seconds. With the LAPD
timeout set off, the TRU does not reset, which is necessary for stand alone
testing.
The SET FS ON command clears the existing display and invokes the
fullscreen display in the AMPS mode. In the fullscreen monitor, the OA&M
commands are displayed and selected by their alphabetic code. The results of
each OA&M command are displayed at specific screen locations.
Figure 1-8 shows the fullscreen displays for the TRU2 and Figure 1-9 shows
the fullscreen for the TRU3. Table 1-2 shows a summary of the fullscreen
commands and these commands are explained in Table 1-3. Table 1-4 to Table
1-6 show and explain the command line mode commands.
The terminal screen is divided horizontally into a status area and a command
area. The bottom line of the terminal display is used as the command area;
you may enter the appropriate letter representing the command. Directly
above the command area is the output message line where status and output
messages, such as selection parameters and error messages, are displayed.
On-line help
Interfacing with the Fullscreen Monitor is simplified by the availability of on-
line help. The user may type “HELP” or “?” in response to any prompt. A brief
paragraph describing the function of the DRU terminal interface is displayed.
Several on-line help categories are available. Each help category contains a
brief, one-line description of each command in that category. The following
categories of help commands are available:
• HELP HELP Lists help categories
• HELP MTCE Lists maintenance commands
• HELP TESTS Lists test commands
• HELP MSR List measurement and query commands
• HELP MONITOR List commands within the monitor subsystem
