We're starting to get a bit annoyed here... The problem discribed by Guy Middleton above also affect our systems: microvax II with DHV11 running Ultrix 1.2 but same problem shows up when using DZQ11 boards this situation is very inconvinient because you never can detect if a printer or plotter is switched off. Because the systems thinks there is a working device on that tty-line, your output get lost. Has anybody solved this problem ? -ron -- Ron Werther PA3DSO | /~~~/ /~~~ /~~~ Advanced Silicon Corporation | / / / * / NIJMEGEN, THE NETHERLANDS | /~~~/ ~~~/ / tel. 3180228212 | / / / / / ..!mcvax!asic001!ron | / / ___/ / /___.
