I am trying to determine why a Access application keeps hanging. The client
is connected to a scale and uses the printer port (LPT1), Com port 1 and com
port 2 to send information back and forth to the scale.
What the previous developer did was use a program called IO.dll to open
communication between the printer port and the scale. The scale signals that
there is a object on it and this triggers the LPT port which in turn causes
the program to open up com port 1 to recieve data and then it calculated out
the tare weight and send the data to Com port 3 for display to the user.
But the software only really worked for 3 days and then it would stop
working after about an hour of use, and the Com ports would stop responding.
Now i am not sure if the connection between the LPT port stops too. But
anything is possible.
Any suggestions on why this application refuses to run now. I believe the
initial installation of the application was August of 2005 if that helps.
