Comments
Use the PF command with host systems that send blocks of data
padded with NULs or other control characters that may interfere
with a graphics sequence (such as unformatted LU 3 mode,
coaxial environments). When the Graphics Mode Disable
command (^PN^-) is used to exit the Graphics Mode, it also
automatically terminates the Free Format command and disables
the Ignore Data commands. This can result in unwanted paper
motion if Graphics Mode is exited between forms or labels, since
host-generated line feeds, form feeds, etc., are no longer ignored
by the firmware. (Refer to the Free Format and Ignore Data
commands on pages 99 and 105 for more information on these
functions.)

The PF command must be issued before the Graphics Mode
Enable command (PY). Host-generated line terminators are then
ignored by VGL and only the following standard graphics format
control commands are recognized:
