Panel Lock The panel keyboard can be locked to prevent inadvertent changes in modem settings. 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, pressing the left and right arrow keys simultaneously will unlock the panel. In locked panel 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. 5-9
