I tested our component and the component from TurboPower and they both 
allow receiving a NULL character as the first input. I don't know what 
you've done that could cause the problem. Unfortunately, I can't send 
you the source code I have because we bought it from a third party. One 
thing you can do, if you don't mind taking the time, is to use the 
AsynchPro package that TurboPower released to the public on Source 
Forge. The source is in Delphi but the Windows calls will be the same.
