The CU then prints the file, but ONLY A FEW LINES of it, not whole file. Is there any possibility of reading whole file via serial interface ? Thank you! Lukas,CT DC EU I DT CZ

Or split file into multiple small files, read multiple times, and then combine them. regards. ----------------------------------------- Awavo serial port monitor
