[MDC-EC] FURTHER: Wrapped file - 2Q11 PG HCC Report - how to correct checksum bug

[n3sb at qis.net]

And even more interesting - although FLWRAP verified the integrity of  
the original file by checksum, the WRAP process removed carriage  
return characters, and other bytes in the data stream that had the  
carriage return value (0x0d). So - right now this doesn't seem to be a  
good option for sending binary files. It's probably something very  
easy to fix, so we could see a future version of FLWRAP that works  
fine with PDF files.

If anyone would like a copy of Wanda KA3AHI's report in the meantime,  
please let me know and I'll send you one directly.

Very interesting - looks like my editor decided to break the first  
line of checksummed data into two lines.

You can fix it by changing FROM:

[WRAP:beg][WRAP:lf][WRAP:fn
2011-04_Quarter_Drill_Report.pdf]

TO:
[WRAP:beg][WRAP:lf][WRAP:fn 2011-04_Quarter_Drill_Report.pdf]

in a text editor.

Hope that helps. The report is worth a read.
