For all those people who replied and helped me with this problem - thanks.
The replies I got broke down into two categories - hardware handshaking
1) Hardware Handshaking - Wire as follows as plotter uses DTR for handshaking :
HP Plotter _________________ Workstation
1 _____________________ 1
5 & 6______________________ 20
20_______________________ 5 & 6
2) Xon/Xoff :
XON/XOFF works fine, but
requires you to send a control string to the plotter to get it to
move into XON/XOFF mode. You should be able to find the appropriate
HPGL commands in your plotter manual; I have found
to work (but this is trial-and-error... I didn't have a neat HPGL
reference). If I send that to the plotter first, life is pleasant.
