The following table shows the programming differences for 4 lines/6 lines:
Command 4 Line 6 Line
@C0 Command did not exist Clears all lines on both a 4 line display
and a 6 line display.
@C5 Cleared all lines on a 4
line display
Clears line 5 on a 6 line display.
Clears ALL lines on a 4 line display.
@C6 Command did not exist Clears line 6 on a 6 line display. Will
not affect a 4 line display
 In order to maintain compatibility with 4 line display terminals in
an existing system, there is a new option in the RF Terminal Setup
for 6 line display terminals. The LCD DISPLAY MODE allows
the user to configure a 6 line display terminal as a 4 line display
(centering the data on the display and conforming to the old
programming command format, i.e. @C05 clears all lines). See
Installation and Setup for details on how to get into LCD
DISPLAY MODE.
 The SIGN ON character for a 6 line display RF Terminal operating
in 6 line display mode (see the previous point concerning LCD
DISPLAY MODE) is different than for a 4 line display. A 6 line
display terminal operating in 6 line mode signs on using ASCII 22.
If the 6 line terminal is configured for 4 line display, it signs on
using ASCII 15. This allows you to use both types of display in
the same system and be able to distinguish between the two
terminal types. See page 6-6 for more information on SIGN ON.
CAUTION: All 6 line display terminals are by default, configured
as 6 line display terminals and will try to SIGN ON using ASCII
22. If you are trying to SIGN ON to an existing 4 line display
terminal system that has not had any changes in its programming
to utilize the 6 line display terminals, the 6 line display terminal
will NOT BE ABLE TO SIGN ON. Make sure to reconfigure the
Terminal using the LCD DISPLAY MODE to operate as a 4 line
display terminal.
