Abstract

A method and apparatus for implementing unified clipboard memory within a keyboard, video and mouse (KVM) switch device is described. The device enables a selected one of several associated computers to read and write from the unified memory inside a KVM switch. A user can share and transfer data quickly between computers even without a network connection or direct connection between the computers.

Claims

1. A method of transferring data from a selected computer to any one of a plurality of computers comprising:

accepting a first user command to transfer the data from the selected computer to a clipboard in a unified memory on a switching system;

transferring the data to the clipboard; and

accepting a second user command to transfer the data from the clipboard on the unified memory to the any one of the plurality of computers.

2. The method of claim 1 further comprising accepting a third command to switch from the selected computer to the any one of the plurality of computers.

3. The method of claim 2 wherein the third command is a request to transfer the data from the clipboard to the any one of the plurality of computers.

4. The method of claim 1 wherein the first user command is a copy command.

5. The method of claim 1 wherein the first user command is a cut command.

6. The method of claim 1 wherein the second user command is a paste command.

7. A system for transferring data, comprising:

a switching system including a unified memory;

a first computer coupled to the switching system;

a second computer coupled to the switching system; and

a peripheral device coupled to the switching system, the peripheral device capable of accepting commands to transfer the data from the first computer to the unified memory on the switching system, the peripheral device additionally capable of accepting commands to transfer the data from the unified memory on the switching system to the second computer.

8. The system according to claim 7 wherein the peripheral device accepts the commands for execution on one of the first computer and the second computer.

9. The system according to claim 8 wherein the unified memory on the switching system includes a clipboard and the commands to transfer the data include a first command to transfer the data from the first computer to the clipboard in the unified memory on the switching system.

10. The system according to claim 9 wherein the peripheral device is capable of accepting a second command to switch the peripheral device from accepting the commands for execution on the first computer to accepting the commands for execution on the second computer.

11. The system according to claim 10 wherein the commands to transfer the data include a third command to transfer the data from the clipboard in the unified memory on the switching system to the second computer.

13. The article according to claim 10 wherein the instructions, when executed by the machine, further case the machine to transfer data by accepting a third command to switch from the selected computer to the any one of the plurality of computers.

14. The article according to claim 10 wherein the third command is a request to transfer the data from the clipboard to the any one of the plurality of computers.

15. The article according to claim 10 wherein the first user command is a copy command.

16. The method article according to claim 10 wherein the first user command is a cut command.

17. The article according to claim 10 wherein the second user command is a paste command.

12. An article comprising a machine-accessible medium having stored thereon instructions that, when executed by a machine, cause the machine to transfer data from a selected computer to any one of a plurality of computers by:

accepting a first user command to transfer the data from the selected computer to a clipboard in a unified memory on a switching system;

transferring the data to the clipboard; and

accepting a second user command to transfer the data from the clipboard on the unified memory to the any one of the plurality of computers.
