Abstract
The invention adopts the virtual COM port instead of the traditional real COM port in a PC host for communicating with a micro-controller in target host. In the prior art, we need to communicate and transfer data between a host and the other one using real COM port and execute the program in the micro-controller. But the present invention uses the Virtual COM port in the PC host to replace the real one and connect to the real COM port of micro-controller in the other PC host. Then it achieves the purpose of programming in the same host including PC host and target host simultaneously.
