Abstract: The present invention discloses a method, a client device, and a data forwarding device for transmitting data through a serial port. The method comprises providing at least two virtual logical serial ports mapped to a physical serial port, providing a main serial port connected to the physical serial port and extended serial ports which correspond to the logical serial ports one by one; encapsulating first data and a specified logical serial port according to a preset serial port protocol to obtain a first data frame; transmitting the first data frame to the data forwarding device through the physical serial port; receiving the first data frame through the main serial port, and decapsulating the first data frame according to the serial port protocol to obtain the first data and the specified logical serial port; and transmitting the first data to the extended serial port corresponding to the specified logical serial port.
