We have 2 pen plotters that get brain damage with multiple plots in the Q. The plotters don't return 'home' between plots. I have a shell scripts that watches the Q and does an lpc stop until the active plot leaves the Q. Then it does an lpc start to let the next one out. I don't want to do all the plotting myself. The gf filters for the plotters are not scripts so I can't put a sleep in them. One plotter is a Calcomp 1044-GT the other is a Computervision P1000. Someone in comp.periphs gave me a C program, but I have no C experience yet. Can I change the group of lpc ?? Greg Ripp Ph (813)628-6100
