This COM Port communication program is developed with VB6.0. It allows user to control 2 COＭ Port. At very beginning I tried to use voice recognition module to wirelessly control 8051 development board, but I found it is a little bit work to soldier bluetooth module into voice recognition module. So I wrote this program to let the voice recognition module(tansmitter) control the 8051 dev board(receiver) through computer com port. This program reads the hardware com port setting, displays it and waits for selecting to be used. It prompts the user to another port if that port is taken by another application so the program won t collapse or crash. If you done heavily com port programming with vb6.0, this one is a very good reference
