I cannot find a voltage/protocol for PS/2 to Serial convertion. I have been looking, but cannot find one. The PS/2 mouse uses 5v and the Serial expects +-12v signals. Although it is a Microsoft dual mouse (aka: PS/2 & Serial) the KVM switches at +-12v. I have put it on a O'scope and looked at the signals. If you can recommend a device, I'd appreciate it. But the real question is during boot, can I select which mouse to use, and/or can I change it on the fly.
