This is my full code. The VB apllication will send char 'A' to my hardware then the hardware will return char 'B' to my application. The problem is I can send the 'A' but I never receive the 'B'. And the function OnComm() are never called.

Below is the other configuration:-

inputLen = 1
SThreshold = 0
RThreshole = 1
