You have to use the setsockopt() function from the WinSock API directly.
For example:

    void __fastcall TForm1::ClientSocket1Connect(TObject *Sender,
TCustomWinSocket *Socket)
    {
        BOOL disabled = TRUE;
        setsockopt((SOCKET)Socket->SocketHandle, IPPROTO_TCP, TCP_NODELAY,
(char*)&disabled, sizeof(BOOL));
    }

> On Visual C++ 2005, there is a function called setsockopt() which does
this stuff.

That is an API function.  It is available to Borland compilers as well.
