wrt 705, “AP”
Automatic pen pickup command, "AP”, causes plotter to auto-
matically raise pen whenever it has been down without motion
for 65 seconds.
This condition is set automatically when
p l o t t e r i s i n i t i a l i z e d .
Sending characters "APO" to plotter will

wrt 705, “PD”
d i s a b l e a u t o m a t i c p e n
Pen down command, PD, lowers pen to paper.
wrt 705,
" V S 1 thru 36 [, Pen No.]"
Select pen velocity command specifies pen speed, in cm/see,

wrt 705, "VA"
S e t s p l o t t e r t o a d a p t i v e p e n v e l o c i t y m o d e . P l o t t e r w i l l
adapt pen speed, automatically, to approximate rate that com-
puter sends coordinate data to plotter. This mode provides
smoother plot than normal velocity mode for plotting coordi-
nates that are generated by a relatively slow program routine
(fewer than 15 coordinates/sec).
wrt 705, “VN”
Normal velocity command,
"VN”, cancels adaptive velocity mode.
Pen speed is now controlled by current pen velocity command.
