You could just power down the display for weeks at a time, and power it up to see what activity was currently being piped to the standard output..... If you can find an old "VT100" or ibm or other brands (can't remember the names, but dec, HP and many others made them" that will work. I've also have a home built "serial data analyzer" that plugs into a serial port, for a blazing 19,200 buad 2 line ascii serial terminal, but it is buried somewhere in my lab..... I have even piped things out one seria console l port (on a headless system) into the serial port of another pc (usually crossing 2 & 3 pins in some from of a "null modem". In fact at one point I has many serial ports on one pc brining in console outputs from many headless Sun servers, for logging. Some "night-mare" I inherited as a graduate student, back when the gasses where coalescing...... Thanks for the trip down memory lane...... hth, James [1] http://www.vanemery.com/Linux/Serial/serial-console.html
