Your data is missing the necessary control characters
used in the normal transmission of the data in FOS or AFOS.

The decoders expect to find products delimited with:

1) On FOS

^A \r \r \n 
and the ending with 
\r \r \n ^C

or 

2) on AFOS
ZCZC
and ending with
NNNN


If your archived data has these characaters stripped out, then you would have to
recreate them, such as is described in:
