Hi,
	I have a HP Prodraft DXL plotter was connected a HP 300
workstation running HP-UX 7.05. It works perfectly. Recently,
I bought a sony NEWS laptop 3250 runnign NEWS-OS 5.01 and connect
the plotter directly to the sony machine. I ported my old hpgl files
from HP machine to sony machine and try to plot them out; but it seems not
work properly. I read the sony document and it says the data flow is
using a Xon/Xoff handshaking method. My question is how can I
set the Xon/Xoff on within the hpgl file. My hpgl files was generated
by C program. Can someone tell me how can write this routine in
C. Or, there may be another reason cause that plotter works unproperly.
Do I need a printer filter for the plotter? Any suggestion will
be appreciated!

Thanks in advance.
