1. A method of determining or confirming an error in transmitted data, comprising the steps of:

  • a) receiving said transmitted data and then partitioning said received data into at least one data line and a last line, each of said at least one data line and said last line having a first fixed length, and the last line containing appended error checking code calculated on said transmitted data;

    b) when said partitioned received data has a remainder, said remainder having any length less than said first fixed length and greater than zero, appending a pad vector to said remainder, the pad vector having a length sufficient to form a first data line with said first fixed length when the pad vector is appended to said remainder;

    c) performing an error checking calculation on said first line, said at least one data line and any data in said last line to generate an error checking vector;

    d) iterating the error checking calculation on said appended error checking code using said error checking vector to provide a calculated error checking result;

    e) determining a state of said calculated error checking result; and

    f) if said calculated error checking result has a predetermined state, indicating that there is no error in said transmitted data.
