Terry,
	Yes, I use a Belken as well. 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.

Regards, Andrew
