Abstract
A method and system for accessing a remote real communication port ('COM port') from a server blade in a server blade chassis by creating a virtual COM port in the server blade. A basic input/output system (BIOS) controller monitors an internal COM port in the server blade for communication traffic. Upon detecting the communication traffic, the BIOS controller reroutes the traffic to a virtual USB COM port created by the BIOS controller chipset. The virtual USB COM port directs the communication traffic to an internal universal serial bus (USB) device in the server blade. The USB device then forwards the traffic to an Ethernet media access controller (MAC) input/output (I/O) on a sideband channel to a remote system, which passes the communication traffic to a real COM port in the remote system.
