I had to play around with it to test it and decided it should just be a 
filter to read stdin and write stdout.  Here's a working script:
**********script
#remove all CR's and LF's and reinsert LF's every n characters
if [ $# -lt 1 ]
then
  echo -e "\n$0\n  Removes all CR's and LF's and reinsert LF's every n 
characters\n  usage:\n    $0 n\nn=new line length\n  $0 reads from stdin 
and writes stdout"
  exit 0
fi
NEWLEN=$1
tr -d "\n\r"|
while read -n$NEWLEN LINE
do
 echo "$LINE"
done
exit 0
**********end script
If you need CR's change the echo line to read "echo -e "$LINE\r".
