Graphics Display
Unbroken straight lines (polylines) and circles can be created by the Support
Tool and displayed at the PT. When an RS-232C or RS-422 Interface Unit is
used, the graphics can be displayed by using the terminal function and trans-
mitting commands from the host. (The terminal function can be used with all
versions. See 4-10-7 Terminal Function.)
Graphics display positions can be designated in dot units. In cases where
graphics and characters overlap, the graphics will be overwritten. Polylines
and circles are both drawn with a width of one dot.
