I use BCOS2 C++ too, but program in C.  Here's my carrier detect function.

// --------------------------------------------------------------------

BOOL    Carrier(HFILE hf)
{
  USHORT    c;

  DosDevIOCtl(hf, IOCTL_ASYNC, ASYNC_GETMODEMINPUT,
                     NULL, 0, NULL, &c, sizeof(USHORT), NULL );
  if( c & 0x0080)
    return TRUE;
  return FALSE;
}
