With the new release Serial Port ActiveX Control 3.0 has become even more useful and functional as we have added 10 more new properties and methods to its arsenal of features.

And last, but not least, Serial Port ActiveX can be easily installed in Delphi 2007.

    I just tried to read the OutBuffSize property after opening the port. It always returns 0. I tried to set it (to 1024) and it still returned zero. I thought this was fixed on

    Thanks, Victor

  • @ Victor –
    Please, be informed that most commonly COM ports on the standard personal computers do not have an output buffer. That is why OutBufferSize property always returns 0 (zero). This was confirmed by multiple tests and results from other users.
