On-line Status Screen 4
Pressing the left or right arrow key in any one of the ON-LINE STATUS screens will
cause the LCD to scroll through the four screens. We will discuss the ON-LINE
STATUS screens 2, 3, and 4 in more detail in chapter 18.
Pressing the ENTER key while in any ON-LINE STATUS screen will cause the LCD to
display the following:
Pressing the up arrow key (MENU) or selecting NO will switch the screen back to the
ON-LINE STATUS screen 1 and the modem remains on-line. Pressing ENTER will
hang up the line and cause the modem to revert to the IDLE STATUS screen to await
your next command.
Pressing the up arrow key (MENU) in any of the four data state screens will change
your current screen to the CONFIGURATION menu. This will be discussed in
chapter 6.
Panel Lock
The panel keyboard can be locked to prevent inadvertent changes in modem set-
tings. This is done by setting the S-register S28 bit 1 to 1 or using the PANEL LOCK
menu from the panel, or by issuing the AT*L1 command from the terminal. Issuing
the AT*L0 command will return the key operation to normal. Alternatively, press-
ing the left and right arrow keys simultaneously will unlock the panel. In locked pan-
el mode, the ENTER key will lose its effectiveness in changing or saving settings; panel
command execution is also disabled. However, viewing in the panel is not affected.
