I am trying to use a Arduino to send commands to a KVM switch (Aten CS1788) . I have had it work on several different computers and different OS, however within the KVM it does not send any keyboard strokes to any computer or within the KVM GUI.
I have tried to print line and press keys neither of them work. Is there something that I am missing? How does the Arduino establish the connection to a computer and how would it be different to any other device? Is there any other way to go about doing this that would work better?
