* ATP6100 only
** SERIALPRINTPROCESS only
The VFU72LINES SYSGEN modifier causes the I/O process to download
automatically the DAVFU when the model 5520 printer is turned on.
For ATP6100 subdevices, use NOVFU72LINES to disable automatic
DAVFU loading; for SERIALPRINTPROCESS, use VFUDEFAULT. For
ATP6100 subdevices, you can change the SYSGEN-configured setting
by including the VFU72LINES attribute in a CMI ALTER SU command.
You can load the DAVFU any time by issuing a CONTROLBUF 1 call.
The LINE1FORMF SYSGEN modifier causes the model 5530 printer
to skip to line 1 of the page after a form feed. For
ATP6100 subdevices, use NOLINE1FORMF to skip to line 4; for
SERIALPRINTPROCESS, use LINE4FORMF. For ATP6100 subdevices
you can change the SYSGEN-configured setting by including the
LINE1FORMF attribute in a CMI ALTER SU command.
The only automatic form movement provided by the file system
is the perforation skip and single spacing. You can disable
these movements with SETMODE operations 5 and 6 (see Appendix
C). Automatic form movement always takes place after a line is
printed.
