Syntax and function of control commands are as follows:
wrt 705, ‘SA PH
Automatic pen pickup command,
" A P ” , causes plotter to auto-
maticallv raise pen whenever it has been down without motion
for 65 seconds. ‘ T h i s c o n d i t i o n i s s et

" A P O ” to plotter will

wrt 705, “PDM

disable automatic pen
Pen down command, PD, lowers pen to paper.
wrt 705,
‘VS 1 thru 36 [, Pen No. ]N
Select pen velocity command specifies pen speed, in cm/see,

wrt 705, ‘VAH
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/see) .
wrt 705, ‘VNN
Normal velocity command,
‘VN”, cancels adaptive velocity mode.
Pen speed is now controlled by current pen velocity command.
