A character is only 1 byte so it fits in SendMessage() 3rd argument
for sending.

Look here:

... and find the part that Gambit (Remy Lebeau) has presented:

    #define MY_CUSTOM_MESSAGE (WM_APP + 100)


    SendMessage(pReceiveAppHandle, MY_CUSTOM_MESSAGE, YourChar, 0);


    void __fastcall TForm1::WndProc(TMessage &Message)
    {
        if( Message.Msg == MY_CUSTOM_MESSAGE )
            ShowMessage("Character arrived: " +
AnsiString((char)Message.WParam));
        else
            TForm::WndProc(Message);
    }
