in IRQ :

  cIn = (*(u8 *)addr);
  xTaskWokenByPost = xQueueSendFromISR( xQueueHDLC, &cIn, xTaskWokenByPost );

if we create a queue with 100 bytes and we send more than 100 bytes in the queue, how FreeRTOS is managing this?
Or we must manage it with a counter?

The character will be lost!  If there is no room on the queue the ISR cannot block so the character has nowhere to go.
