Vertical Format Units5–10
The
Slew Relative configuration and
the status of data bits 1 through 4 determine the number of lines
slewed
as described in T
able 5–6. (Note that the state of data bit 5 is the dif
ference between line slew
-
ing
and using the interface lines as DVFU channel codes.) As long as the DVFU is selected, this type
of
vertical paper motion will occur, regardless of whether the DVFU memory is loaded or not.
If the Double High for One Line attribute is active, n
+ 1 lines are slewed rather than
n
lines.

Serial Matrix Vertical Formatting
In
Serial Matrix protocol, vertical formatting is always enabled. Forms control is accomplished by a
set of programmed vertical tabs. Various lines of the form are assigned vertical tabs which are then
accessed
by control
code for rapid paper advancement to the tab position. T
wo codes are used for con
-
trolling
vertical tabs: ESC B for single channel tab setting and VT to execute
a vertical tab. These codes
and their parameters are described in the Programming
chapter
.
The VFU Loaded indicator on the con
-
trol panel will not glow when vertical tabs are loaded for forms control.
