   @acassis Yea I have a specific protocol followed in my bus that has break in the start of every frame of data. I did a work around by checking if no bytes were received in the last x ms/us, then just assume that it is a break byte and it worked in my case.
   
   Also, I do not read the 0x00 from UART when I receive a break byte. So is the break detected internally and already handled somewhere in the Serial Device Driver? How do I check it?
   
   With the interrupts, I did not understand how to use interrupts with UART which I think is due to the lack of documentation!?
   The [documentation for Timer Driver](https://nuttx.apache.org/docs/latest/components/drivers/character/timer.html) is really good. Something of that sort for [Serial Device Driver](https://nuttx.apache.org/docs/latest/components/drivers/character/serial.html) would be great.
   
   Please let me know if I am missing something? Like should I go through the general implementation of Serial drivers on Linux and the same thing could be used for NuttX? Sorry for asking (simple?) questions. I am just used to embedded software programming and learning RTOSs lately. I do not have experience with Linux or its drivers.
