Parameter 18: Line Display

Parameter 18 specifies the line display character. When the PAD receives the line display character from the local DTE device, the PAD sends the local DTE device the line display service signal. This transmit to the local DTE device the last entire line of characters the PAD received from the local DTE device. Receipt of the line display character is valid when the PAD is in the PAD data transfer mode and editing (parameter 15) is enabled or the PAD is in the PAD command mode.

The function priority for duplicated characters (because of duplication of parameter assignments) follows the order of priority listed in the priority table provided for parameter 3.
