    Have a look at the code posted in this thread, in particular post #16 I think there might be something you can use in there, a tidy little ring buffer perhaps.

    Thanks Joe,

    I have got "rather" consistent reading with HSERIN command
    For example I got @123456789 , then 89 @12345 then 3@ 234 789

    How to "filter" or how to put a qualifier so I can get numbers after @ sign ?

    You see it is looping and catching data mid stream, look at the manual under herserin, and serin2 for instructions re: wait . If your data is a fixed length packet you can tell herserin how many units to receive before proceeding to the next operation.

    Thanks Joe, it works now.
    The problem was the unshielded cable . I changed the cable to shielded, and ground it, the readings are now consistent
