"COM3" is correct
You might try using
HANDLE h;
h = CreateFile( "COM3", GENERIC_WRITE, 0, 0,
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0 );
if( h != INVALID_HANDLE_VALUE )
{ DWORD byteswritten;
WriteFile( h,"ATDT01555444333\r",
sizeof("ATDT01555444333\r")-1, &byteswritten, 0 )
/* also notice the change to \r */
CloseHandle( h );
}else{
//handle the error
};
