Another problem we had is that we could not detect a power off on the printers. Our printers are not on the unibus but have rs232 interfaces and plug into terminal ports. We got around both the problems by adding a terminal type 'p' to getty. If the terminal type is a 'p', our getty does not exec login but rather starts the printer spooler. Because the first terminal opened by the spooler is the printer, the print spooler was part of that terminal's process group and could then see the HUP signal when the printer's power was shut off. Also, if the daemon dies, init will spawn another getty to start it right away. To stop a prin- ter, one merely needs to edit the /etc/ttys file and send a sig- nal to init. Has anybody got a copy of enable/disable that they could send me? Derek Andrew U of Saskatchewan
