Appendix C Paper Motion Using the PI Line (Relative Line Slewing)
The binary slew commands can skip from 1 through 15 or 1 through 16 lines
on the form, depending on how the Slew Range configuration option is
configured. Refer to Table 24 which illustrates how lines are skipped for each
value. (Note that the state of data bit 5 is the difference between line slewing
and using the interface lines as EVFU channel codes.) This type of vertical
paper motion occurs whenever the line slewing command is used regardless
of whether the EVFU memory is loaded or not.

Note *The ASCII values in Table 24 assume that all undefined bits
are set to 0. When the PI line is enabled, data bit 8 is the PI
line on a serial interface, and data bit 8 is undefined on a
parallel interface.
