When I get debug message from debug port, some data is replaced as '?' .
How to fix it ?

#define DEBUG_INFO_TX_PIN GPIO_PD3
speed is 1000000bps

result is
PIR?Data?:?0x7FDC?,?TempData?:?0x1?32,?Value?= 0x7F71A32?,?pirSensorMode-0<CR><LF>

Opening interrupt protection on this code should improve it.
