Yes. TWSocket is designed to buffer incoming data for you if you use LineMode. That is when you have your data terminated with a certain character (or a string of characters). If you dont use LineMode then yes you have to buffer on your own. > I know that, but with 100%CPU usage, the handling of messages is stopped > anyway as well as no other thread will be able to take control.

Agree, but there is also a componentOptions property wsoNoReceiveLoop which will fire OnDataAvailable again using a custom message handler. In that case message pump stay working. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Wednesday, September 26, 2007, 15:38, Olivier Sannier wrote: > Wilfried Mestdagh wrote: >> Hello Olivier, >> >> >>> The NotifyDataAvailable sets a flag in an object associated to the >>> client socket that will then read the available bytes.
