i wrote a litte soft for monitoring alarms connected to // port under
linux.( see: http://www-iag.unice.fr/guardian/guardian.html )
it's a system quite simple if the circuit on one of the 5 lines (BUSY,
PAPER OUT, SELECT, AUTOFEED, ERROR) is open the data read is true and
false if it is closed.It worked well during one year, but now the data
are always read as false, so if an alarm occured it will not be
monitored as before. The problem is that it happens randomly ,on any
lines, and randomly after a period of time,when it happens it is not
reversible until i reboot the system with no power off needed.
So the linux kernel (or the BIOS?) seems to be able to do a soft reset
on the // port at boot time, if i can do this reset in my own program
the system will work again but i can't find on the internet how to do
this , perheaps someone in the mailing list know that or have an advice?
