hp/gl is one of the protocols(plotter languages) it has to be selected or deselected on both ends software and plotterok finally got it going...
after a few hours of playing around i found the problem!!!
when u add the hs15 plus HP/GL inside flexi production manager.
CTS , RTS and DSR are selected from default,
after i deselected them it worked...
can anybody explain to my what this is? and why is it selected from the beginning?
is this important? why they are selected from default?
thanks again for all the help
