- First try to talk to the plotter without using the spooler, i.e. :
-
- # sleep 100000 </dev/plotter &
- # stty <nice_options> </dev/plotter
- # cat file >/dev/plotter
-
- The "dumbplot" model issues "IN;" and "PG;" HP-GL (HP Graphics
- Language) instructions, which the Calcomp plotter might not understand
- (Does the Calcomp plotter understand HP-GL?).
-
- If you have a terminal with the same baud rate as the plotter, then
- you may want to use that first in order to know for sure that you have
- the right wiring, baud rate, etc. and are receiving correct data. If the
- terminal is an HP terminal with an HP terminal mode (i.e. not only
- emulating non-HP terminals), then you may want to use its "DISPLAY
- FUNCTNS" mode, so you can see non-printable characters.
