Virtual KVM functionality for computer systems

A system for implementing virtual keyboard video mouse (KVM) switching functionality between at least two computers using a processing device in communication with a memory device, comprising:

• a rack-mount computer system comprising at least one device driver operable on the rack-mount computer system;
• and
• a portable computer configured to be detachably coupled to the rack-mount computer system and comprising an application operable on the portable computer, wherein:
• the at least one device driver is adapted for redirecting first keyboard, first video, and first mouse signals from the rack-mount computer system to the portable computer over a standardized serial bus detachably connecting the rack-mount computer system to the portable computer, wherein each of the first keyboard, first video, and first mouse signals are carried at predetermined frequencies,
• wherein the application is adapted for receiving the redirected first keyboard, first video, and first mouse signals from the at least one device driver, identifying and separating the first keyboard, first video, and first mouse signals on the portable computer, passing the first keyboard, first video, and first mouse signals to an operating system on the portable computer, and overriding control of second keyboard, second video, and second mouse signals for the portable computer in response to receiving the first keyboard, first video, and first mouse signals, and
• further wherein the first keyboard, first video, and first mouse signals are used by the operating system to manage the rack-mount computer system,
• wherein the first keyboard signal is carried at approximately 27.195 MHz, the first mouse signal is carried at approximately 27.145 MHz, and the first video signal is carried between 150 and 200 MHz.

A non-transitory computer program product for implementing virtual keyboard video mouse (KVM) switching functionality between at least two computers using a processing device in communication with a memory device, the computer program product comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first executable portion for redirecting first keyboard, first video, and first mouse signals for a rack-mount computer system over a standardized serial bus connecting the rack-mount computer system to a portable computer, wherein each of the first keyboard, first video, and first mouse signals are carried at predetermined frequencies;
• a second executable portion for identifying and separating the first keyboard, first video, and first mouse signals on the portable computer;
• a third executable portion for passing the first keyboard, first video, and first mouse signals to an operating system on the portable computer;
• a fourth executable portion for overriding control of second keyboard, second video, and second mouse signals for the portable computer in response to receiving the first keyboard, first video, and first mouse signals;
• and
• a fifth executable portion for utilizing, by the operating system, the first keyboard, first video, and first mouse signals to manage the rack-mount computer system,
• wherein the first keyboard signal is carried at approximately 27.195 MHz, the first mouse signal is carried at approximately 27.145 MHz, and the first video signal is carried between 150 and 200 MHz.
