If you address past the end of an array that is longer, the null will be sent. This is an Ascii comand to clear screen, thus black screen after data is sent. Access the variable to the end sizeof()-1 for the first char address is variable[0]. My first simple tv display of serial input program mod cought $00 cleared screen too. Also I had to add delay between char's for the serialmirror demo was too slow recieving and echoing.
