perl -0777lpwi -030e0  your_file

Study of man perlrun will explain why this works.

Very nice. This merits a closer look:

    perl -0777lpwi -030e0 file

    0777    Set $/ to 0777.
    l       Chomp $\ and set $\ = $/. Thus $\ = 0777.
    p       Loop over file and print.
    w       Turn warnings on.
    i       Make the changes in-place.
    030     Set $/ to 030 (^X). $\ is still 0777.
    e0      Empty program.

So in effect this splits the file into records divided by ^X, chomps ^X from the end of each record and prints out the records with 0777 appended at the end. However, (and I'm not certain about this) since there is no character with that value it actually appends ''. Thus, the ^X's are removed from the file.

So in a way the program is functionally equivalent to:     perl -i -pe 's/\30//g' file

I say functionally equivalent since there is no aesthetic equivalence. :-)

This seems to suggest your problem is in some other part of your pipeline (maybe some other program is processing your output?), or you don't use the standard while(<>) method of reading lines from a file.

You can ofcourse filter out the ^X characters by doing something like:

while (<>) {
    s/\30//g;
    # ... do stuff
}

   s/\cM//g; # removes ^M's
   ...  
}

That seems very odd to me. Why is your script coughing on C-X characters? Mine don't, and I don't think C-X is understood as a special character on Unix. If you using a strange OS that does so, you may want to binmode the filehandle before reading from it. The other case I can think of is if your data is coming down a serial port with Xon/Xoff enabled; in which case the problem is not with your script, but the port's configuration. As I haven't done any serial port work I'm not sure what you'd do to change the configuration to suit your needs, but maybe with this pointer you will be able to look in the right place.
