My apologies, I wasn't clear.

The file is plain text that has curses detritus all the way
through it.  A sample is:

[23DOPC Save and Restore  [0m[m
[23DOPC Shutdown
[19DOPC Date               [0;7m[m
[23DPort Configuration    [0;7m[m
[23DIP Routing Admin
[C    Unix Shell
[10DOPC PM Coll. Filter
[19DTL1 Configuration
[20DLog Archive

Your suggestion is excellent at getting rid of the \C-?
characters.  Any ideas on the escape strings?
