Abstract:
1. A method of sharing device data and focus command data from a peripheral device by a plurality of computers including a first, second, and third computer, said peripheral device coupled with the first computer, the method comprising: providing for coupling the peripheral device to the first computer using a first hardware interface; providing a first device emulator coupled between and separate from the first computer and the second computer, the first device emulator adapted to pass the device data and focus command data from the first computer to the second computer in a format used by the peripheral device, the first device emulator further comprising, providing a second device emulator coupled between and separate from the second computer and the third computer, the second device emulator adapted to pass the device data and focus command data from the second computer to the third computer in a format used by the peripheral device, receiving the device data and focus command data at the first computer; processing device data and focus command data received from the peripheral device; determining whether the device data should be processed by the first computer using the focus command data; and passing the device data to the first device emulator for transmission to the second computer if the focus command data identifies a computer different than the first computer.
