We are trying to operate a hp 7585B plotter directly connected to a VAX running VMS 4.6, but are having nothing but problems. The plotter goes wild at certain points in the test plot file that indicate something about the buffers filling up. We have tried changing buffer sizes using hp control language with little success and now think that the plotter and the VAX do not handshake properly. As a last resort, we will connect the two through a data kit system that will provide for buffering; however, this is not my idea of the most effective or efficient way to interconnect the two. I hope someone is doing or has done something similar and can offer some advice. This problem is beginning to make a good number of people restless, myself included. Thanks. M. E.

hmm, we have several that work just fine. you do have to be VERY careful about setting up the x-on/x-off handshaking. Them hp manual gives several good examples about using the N and M commands to set the various characters and 'levels'... Also verify that the vax terminal line is set to x-on/x-off (I seem to recall that its ttsync) -ed cetron@wasatch.utah.edu
