Abstract
A system and a method for virtual serial port management include setting a virtual universal asynchronous receiver/transmitter (VUART) and a software multiplexer (MUX) and setting the VUART to perform functions corresponding to different values of the software MUX. The method further includes receiving commands sent to the server regularly and assigning a first predetermined value to the software MUX when the received command is not an Intelligent platform management interface (IPMI) command. The management method further includes assigning a second predetermined value to the software MUX when the received command is the IPMI command but not a serial over LAN (SOL) command, and assigning a third predetermined value to the software MUX when the received command is the SOL command.
