First, I want to thank all of you who answered to any of my questions, I appreciate it and it helps me to progress a lot. My actual question is about reading in a loop. I read a string (Visa read) of a specified lenght of bytes from my serial port. This visa read is in a while loop, and I'd like to cummulate all the readings in a text indicator (and eventually in a file). For now, I'm only able to get the last reading, 'cause if I put my text indicator in the loop, it overwrites at each iteration and if I put it outside, it keeps only the last reading. I'm sure it's just about concatenating or building text but I did not find how. Thanks once again for help.
