Abstract

A remote control device is described. The remote control device uses a network chip directly mounted on a motherboard of a server computer to remote control the server computer without any additional network card requirement. The remote control device includes a basic input output system (BIOS), a COM port, a baseboard management controller (BMC), and a network chip. The BIOS redirects video data to the COM port and then the same to the BMC. The BMC transforms the video data into network packets according to a Q-Telnet protocol. The BMC recognizes the Q-Telnet protocol and a standard Telnet protocol effectively. Therefore, the network chip uses a UDP 623 port to control the BMC and a TCP 23 port to transmit data and commands using the standard Telnet protocol.

Claims

1. A remote control device using a remote computer to control a server computer, the remote control device comprising:

a basic input/output system (BIOS), which redirects video data of the server computer;

a COM port, which connects to the BIOS to receive the redirected video data;

a baseboard management controller (BMC), which connects to the COM port for transferring the redirected video data according to a predetermined protocol into network packets, the BMC being able to recognize the predetermined protocol and a standard Telnet protocol; and

a network chip, which connects to the BMC, using a side band and the BMC to transmit the network packets, and transmitting the network packets to the remote computer by way of a computer network for displaying the video data on a monitor of the remote computer.

2. The remote control device of claim 1, wherein the video data include the monitor image of the server executing the disk operating system (DOS).

3. The remote control device of claim 1, wherein the video data include the monitor image of the server executing the power on self test (POST).

4. The remote control device of claim 1, wherein the BMC supports the intelligent platform management interface (IPMI).

5. The remote control device of claim 4, wherein the network chip complies with the IPMI side band standard and is mounted on a motherboard of the server computer.

6. The remote control device of claim 5, wherein the network chip uses the UDP 623 port as a transmission interface.

7. The remote control device of claim 1, wherein the predetermined protocol is a Q-Telnet protocol incompatible with the standard Telnet protocol.

8. The remote control device of claim 7, wherein the network packet using the Q-Telnet protocol contains at least a Q-Telnet header, a RMCP header, and a UDP header.

9. A remote control system comprising:

a remote computer, which contains;

a keyboard;

a host computer; and

a monitor;

a computer network; and

a server computer with a remote control device, the remote control device including;

a basic input/output system (BIOS), which redirects video data of the server computer;

a COM port, which connects to the BIOS to receive the redirected video data;

a baseboard management controller (BMC), which connects to the COM port for transferring the redirected video data according to a predetermined protocol into network packets, the BMC being able to recognize the predetermined protocol and a standard Telnet protocol; and

a network chip, which connects to the BMC, using a side band and the BMC to transmit the network packets, and transmitting the network packets to the remote computer by way of a computer network for displaying the video data on a monitor of the remote computer;

wherein the remote computer uses the keyboard to enter a command that is converted into an input network packet by the host computer according to the predetermined protocol and transmitted by way of the computer network to the remote control device, the BMC decodes the input network packet in order to control the server computer.

10. The remote control system of claim 9, wherein the video data include the monitor image of the server executing the disk operating system (DOS).

11. The remote control system of claim 9, wherein the video data include the monitor image of the server executing the power on self test (POST).

12. The remote control system of claim 9, wherein the BMC supports the intelligent platform management interface (IPMI).

13. The remote control system of claim 12, wherein the network chip complies with the IPMI side band standard and is mounted on a motherboard of the server computer.

14. The remote control system of claim 13, wherein the network chip uses the UDP 623 port as a transmission interface.

15. The remote control system of claim 9, wherein the predetermined protocol is a Q-Telnet protocol incompatible with the standard Telnet protocol.

16. The remote control system of claim 15, wherein the network packet using the Q-Telnet protocol contains at least a Q-Telnet header, a RMCP header, and a UDP header.

17. A remote control device using a remote computer to control a server computer, the remote control device comprising:

a basic input/output system (BIOS), which redirects video data of the server computer;

a COM port, which connects to the BIOS to receive the redirected video data;

a baseboard management controller (BMC), which supports the intelligent platform management interface (IPMI), connects to the COM port for transfer the redirected video data according to a Q-Telnet protocol into network packets, the BMC being able to recognize the Q-Telnet protocol and a standard Telnet protocol that are incompatible with each other; and

a network chip, which is mounted on a motherboard of the server computer, connected to the BMC, and compatible with the IPMI side band, and uses a side band and the BMC interface to transmit the network packets, transmitting the network packets to the remote computer by way of a computer network for displaying the video data on a monitor of the remote computer.

18. The remote control device of claim 17, wherein the video data include at least one monitor image of the server executing the disk operating system (DOS) and the server executing the power on self test (POST).

19. The remote control device of claim 17, wherein the network chip uses the UDP 623 port as a transmission interface.

20. The remote control device of claim 17, wherein the network packet using the Q-Telnet protocol contains at least a Q-Telnet header, a RMCP header, and a UDP header.
