A bridge module is bridging communications between computing systems using UDP (user datagram protocol) communication protocol and computing systems using TCP (transmission control protocol) communication protocol. Communications between the bridge and the computing system having UDP communication drivers are handled with the UDP protocol. Communications between the bridge and the computing system having TCP communication drivers are handled with TCP protocol. The UDP computing system, i.e. the computing system using UDP protocol, opens communications by performing a handshake routine with the bridge module. Once the UDP communication between the UDP computing system and the bridge module is established, the UDP computing system sends data packets to the bridge module. The bridge module converts these packets from UDP protocol to packets in TCP protocol and sends them to the TCP computing system, i.e. the computing system using TCP protocol. The TCP computing system can send data back to the UDP computing system by sending packets to the bridge module using the TCP protocol. The bridge module will convert the TCP data packets from the TCP computing system to data packets in UDP protocol and forward them on to the UDP computing system. One exemplary environment for the invention is console redirection from a computing system, that is running firmware such as BIOS, to a computing system that is running an operating system on top of BIOS.
