PURPOSE: A method for sharing a computer serial port is provided to share the serial port by using a server unit of each computer and judging the serial port is an idle state during a setting time of a timer. CONSTITUTION: A corresponding program requests the seizing and use of serial ports to a computer control unit for transmitting serial data(S100). The computer control unit judges whether serial ports are an idle state or the specific program is a seizing state(S110). If the serial ports are seized and used, the computer control unit counts a certain time set in a timer of a server unit(S120). The computer control unit judges whether the serial ports are the idle state or a seized state by the program(S130). If the serial ports are the idle state and the seized state by the specific program, the computer control unit admits that the corresponding program seizes the serial ports(S150). The program receives the admission of the seizing of the serial ports and transmits the serial data through the serial ports(S160).
