From: Alan Parker <parker@NRL-CSS.ARPA> Is anybody using a Benson (sometimes called Varian) plotter on 4.2? (I can't believe I'm the only person dumb enough to buy one!) The supplied driver on the 4.2 distribution doesn't work at all. It generates a large number of unibus errors and NPR timeouts. This was also the case with the 4.1 distribution (at least the version that we got). Peter Eichenberger @ Stanford gave me a fixed version of the driver for 4.1 which we have been running for the last few years without any problems. I modified this driver for 4.2 as best I could. It seems to work OK, until the plotter is taken offline while its printing. When that happens, the device goes away. ("va0: no such device or address"). The only way to get it back is to reboot. Not acceptable. So much for where I stand. Does anyone have any suggestions? Do *you* have a Benson plotter running on your system? If so, I would like to compare notes. Thanks. arpa: parker@nrl-css uucp: ...!decvax!nrl-css!parker -Alan
