Virtual serial port system and communication method for same

The invention discloses a virtual serial port system and a communication method for the same, which are used for realizing a cross-OS (operating system)-platform virtual serial port system and avoiding incapability of the virtual serial port system in commutation on different OS platforms. The virtual serial port system comprises a serial port client-side component module and a serial port server-side component module, wherein the serial port client-side component module positioned on the client side is used for providing an interface interacting with the serial port server-side component module for a user, generating a virtual serial port message according to operations of the user and transmitting the message to the serial port server-side component module; and the serial port server-side component module positioned on the server side is used for analyzing for the virtual serial port message transmitted by the serial port client-side component module and determining an operating system platform corresponding to the message.
