Abstract
A device and method for controlling the baud rate between a portable telephone and an external device is provided. A first input/output (I/O) port is connected to the portable telephone which transmits and receives data to/from the portable telephone, and a second I/O port is connected to the external device which transmits and receives data to/from the external device. A controller interposed between the first and second I/O ports, detects a first baud rate of the portable telephone, converts an initial baud rate of the first I/O port to the first baud rate, and transmits the data to the portable telephone via the first I/O port. The controller also detects a second baud rate of the external device, converts an initial baud rate of the second I/O port to the second baud rate, and transmits the data to the external device via the second I/O port.
