        !            12: A tool was developed which rebuilds the downloadable file for the PT
        !            13: terminal.  Effectively it reduces the size of the  file by approximately
        !            14: 24 percent (14000 bytes).  Logically what happens is that the data field
        !            15: which is transmitted goes from 32 bytes to 256 bytes.  This appears to be
        !            16: the point of diminishing return performance wise.
        !            17: .LP
        !            18: This tool (recnv) allows us to modify only the hexfile, without having to
        !            19: change the EPROM, dlpt, pt.init or any other files.  The performance
        !            20: gain varies with baud rate and whether or not reliable mode is used when
        !            21: downloading.
        !            22: .LP
        !            23: Below I list the performance data gathered so far.  The first set of data
        !            24: is using dlpt with the standard 3.02 download file.  The second set of
        !            25: data is using the converted hexfile.  The third column were the downloads
        !            26: using an CPU port (no percentages taken).  The fourth column is the performance
        !            27: gain in percentage of Recnv over Standard.  The measurement were taken on
        !            28: an Oneida runing PERPOS-P 2.01, while connected to a PVIOC-X port (all times arein minutes:seconds).
