mrossen Active Member Licensed User Longtime User Apr 1, 2014 #1 Hi, If I use AStreams with prefix the length of what I send and receive will be addto to my string. My question is: If I send ex. char * how will it look when I reviece it. Will it be ascii char 01 and char *? And the same if I want to send to at device that expect prefix. Do I have to send ascii char 01 and char * Mogens
