Its been asked many times how one opens a connection to the WindowServer when no one is logged in ( by myself at least three times ). Everytime I get no useful answer, just a lot of questions of the form "Why would you want to do that?" In the hopes that someone will find my cause worthy and answer my question, here goes: I would like to connect a UPS to my NeXTstation that has a serial cable through which it notifies the computer when the power supply has been interupted. On the computer I would like to have a daemon running which monitors the serial port; when the power goes out it will sound an alarm and present a count-down timer approximating when power will be lost. This program will need to be able to inform me of a problem even when I'm not logged in ( so I can do a clean shutdown at the very least ). In order to do that, I need to open a window when no one is logged in. I do not care if I can't use the AppKit, I think I can manage a simple timer in PostScript myself. Having the daemon just assume it can shut the computer down if no one is logged in at the console is not acceptable, people may have telneted to the machine ( and besides, I don't know how to do that either ). Please, if you know how to do this, tell me. Chris -- Christopher D. Audley Elec & Comp Engineering The Johns Hopkins University Internet: audley@jhunix.hcf.jhu.edu
