I'm sending multiple sensor data from Arduino to the [serial] object; to signify the end of a 'packet' of data the code loop ends with Serial.print(255, BYTE) - this allows me to use [select 255] and [unpack] in Max to get my sensor data independently and in order such that sensor 1 on pin 1 arrives first, sensor 2 on pin 2 second etc etc. However, as the code is running all the time, when I initialize the [serial] object in Max, sensor 1 may arrive 3rd, sensor 2 4th etc - i.e. still in order but out of sync. I can signify the START of a packet (with a space char or whatever) but how would I use this signifier in Max to ensure that sensor 1 data is always first, regardless of when I initialize the serial object?

ps have rephrased this and posted on the Arduino, adafruit etc forums

tried to 'decode' several prefabs such as Arduino2Max, 'SimpleMessageSystem', Maxuino etc to see how they do it, but the answer hasn't leapt out at me....

What I do is sending strings like "A0990", "C0001, from the arduino (the letter used as a tag to identify the pins). As you see, I even do "0" padding, so I know I have to read 5 char on the Max side and parse them.
