Hi i tried to do one sequence of serial communication , first send a character, second wait a time, and the last the read, all this communication is for a RFID device, the problem is when i run the VI always send the character and wait time, but never read, all parts of this sequence works fine when i tested in specially the reading part, i really i don't know what is wrong with this sequence, i added the images of the subvi's I've done.
Thanks
