Why if I try to do:     xSerialPutChar( xUART2, ‘a’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘b’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘c’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘d’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘e’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘f’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘g’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘h’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘i’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘l’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘m’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘n’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘o’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘p’, mainNO_BLOCK ); in a task running with other tasks, doesn’t it work? (It may write on my terminal another char or the right sequence, but truncated or it may even crash… ) Why does     xSerialPutChar( xUART2, ‘a’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘b’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘c’, mainNO_BLOCK );     xSerialPutChar( xUART2, ‘d’, mainNO_BLOCK ); work? And why if this task is the only one running, with all the xSerialPutChar, does this work well? Thank you in advance, Pietro

Any clues as to which port you are using.  Processor? Compiler?  Did you write the code yourself, or is this in the download?

Does it work if you use a block time.  You are probably just not sending all the data. Which port are you using?

I’m using PIC18F6527 with MPLAB 7.62, and I write my code. Can you give me any advices? Thank you, Pietro
