I see.
So this is what I do:
+ in TaskConfig I have {"Y", fnMyTask, NO_QUE, (DELAY_LIMIT)(1 * SEC), UTASKER_STOP} that starts the task at the beginning.
+ Then, in my task I define the TTYTABLE for Tx and Rx, and I assign DebugHandle = SerialPortID; at this point I can write to UART.
+ Now, what I am trying to do but I don't know how, is to run the task again so I can enter a state where I can catch the UART Rx interrupt/messages. The task to wake in TTYTABLE, as I said in the other post, does not get triggerd so I don't even enter the routine containing the fnRead(SerialPortID, ucInputMessage, MEDIUM_MESSAGE).
I don't need something periodic, but something that waits for SERIAL interrupts. I was using the uTaskerMonoTimer (improperly) to set the task in "listening for interrupts", that's why my task is periodically relaunched or does not receive UART interrupts
