What magic incantation is required to start a sunview tool and repeatedly write to it like it was a hard-wired device? Perhaps an example would be clearer. Here's how I guessed it might work (but doesn't): sunplot & # sunview plot(3) viewer starts up [1] 1418 ps ... 1418 p3 T 0:04 sunplot 1419 p3 R 0:00 ps ... graph <xy >/dev/ttyp3 # send a graph to sunplot graph -b <xy2 >/dev/ttyp3 # overlay another graph, and so on This is (obviously) no good, since all the processes started from that cmdtool use ttyp3. I've tried redirecting from /dev/ptyxx (a wild guess): that almost works, but behaves oddly on several counts. It's a trivial point, but I'm curious. -- Joe Smith University of Pennsylvania jes@mbio.med.upenn.edu Dept. of Biochemistry and Biophysics (215) 898-8348 Philadelphia, PA 19104-6059
