Hi,
I'm trying to use the com port, but when I read this buffer and there are
not data, the handle don`t  return the control to the next code line.

Here is my source code.
------------------------

bool TCom::ReciveBin( unsigned char *argAStr_Data, unsigned long
argul_BytesWait , unsigned long &argul_BytesReturned)
{

  ReadFile ( hCom, argAStr_Data, argul_BytesWait ,
&argul_BytesReturned,NULL );

  if ( argul_BytesWait == argul_BytesReturned )
    return true;
  else
    return false;

}


My handle and com sets are:
------------------------------

bool TCom::OpenPortDefault()
{
  COMMTIMEOUTS new_timeouts = {0};
  bool    fSuccess;

  hCom = NULL;
  hCom = CreateFile( "COM1",
                     GENERIC_READ | GENERIC_WRITE,
                      0,
                      0,
                      OPEN_EXISTING,
                      0,
                      NULL );

  if( hCom == INVALID_HANDLE_VALUE )
    return false;
  else
    return true;

  fSuccess = GetCommState( hCom, &dcb );
    dcb.fBinary      =  true;
    dcb.BaudRate  =  9600;
    dcb.ByteSize    = 8;
    dcb.Parity        = NOPARITY ;
    dcb.StopBits   = ONESTOPBIT ;
  fSuccess = SetCommState(hCom, &dcb);

  GetCommTimeouts(hCom,&old_timeouts);
    new_timeouts.ReadIntervalTimeout         =        250;
    new_timeouts.ReadTotalTimeoutConstant    = 1000;
    new_timeouts.ReadTotalTimeoutMultiplier  =  1000;
    new_timeouts.WriteTotalTimeoutMultiplier = 0;
    new_timeouts.WriteTotalTimeoutConstant   = 0;
  SetCommTimeouts(hCom, &new_timeouts);
}


OBJECT PROPERTIES
-------------------------

    private :
    DCB          dcb;
    HANDLE       hCom;
   COMMTIMEOUTS old_timeouts;


thaks for all
