I am communicating with a computer using the com port (using hyper terminal, on a win nt os). When the computer recieves what I send to it, it immediatly sends me back information.
Now, I am trying to do the same thing using visual basic using the Microsoft CommControl 6.0 component. The setting are exactly the same as hyper terminal. I tried using both the OnComm event to recieve data as well as just checking the buffers myself. However, I NEVER recieve any data.
Could you tell me what might be causing this problem? This computer sends the data IMMEDIATLY. Could the problem be that vb or the component cannot keep up with the speed that the data is being sent back at?
