Claim Text:
1. An apparatus for serial communication configured to perform a serial communication through mutually different communication methods, the apparatus comprising: a communication converter configured to transmit a data using mutually different serial communication methods through a common port in response to a provided communication method selection signal, or receiving a data from outside; and a controller configured to provide the communication method selection signal and the transmission data to the communication converter in response to a set parameter, and to receive the data transmitted from outside through the communication converter, wherein the mutually different serial communication methods comprise an RS-232C communication method and an RS-485 communication method, and the communication converter includes: a RS-232C driver configured to perform communication using the RS-232C communication method and a RS-485 driver configured to perform communication using the RS-485 communication method; a switching unit configured to provide the data to the controller and to outside by selectively switching between the RS-232C driver and the RS-485 driver; and a communication port controller configured to activate and deactivate the RS-232C driver and the RS-485 driver respectively in response to the selection signal, and to control transmission/reception operation of data in response to a control signal of the controller, wherein the communication port controller includes an RS-232C controller configured to activate and deactivate the RS-232C driver in response to the selection signal of the controller, and an RS-485 controller configured to control transmission/reception operation of the RS-485 driver in response to the control signal provided from the controller.
