    Hi Michael & Oliver.

    Just to check what is going wrong here could you try to execute the following two commands:
    printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
    /usr/bin/printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
    echo -ne \\xa8\\x51\\x37\\x00 > x ; hexdump x

    Please try as above and also with full path to printf (/usr/bin/printf)

    On my system it looks like this:

    $ printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
    0000000 51a8 0037
    0000004
    $ /usr/bin/printf \\xa8\\x51\\x37\\x00 > x ; hexdump x
    0000000 51a8 0037
    0000004
    $ echo -ne \\xa8\\x51\\x37\\x00 > x ; hexdump x
    0000000 51a8 0037
    0000004

    Sam
