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.
