ok, i understand,reason i ask about "getting rid of "@" is because i want to use that as a startbyte..
Story is....i am planning to build a computerized greenhouse and there will be about 10 to 15 diffrent sensors attached to the arduino.
so from what i have understood i want something like.
s122.11@s266@s323.11......
where s1 s2 and s3 etc is the diffrent sensors
hope you understand
