I finally have a script that deals with the terminal and cpan opening up with the need to overwrite a lockfile. This is a grandchild of portableshell.bat that is recommended for beginning strawberry perl on windows. I have alternated between using set TERM=dumb and commenting it out. Also, I don't want the script erasing the value of PERL5LIB, so I comment that out as well.

@echo off
rem set env variables
rem set TERM=dumb
set LINES=40
set COLUMNS=80
set PERL_JSON_BACKEND=JSON::XS
set PERL_YAML_BACKEND=YAML
rem avoid collisions with other perl stuff on your system
rem set PERL5LIB=
set PERL5OPT=
set PERL_MM_OPT=
set PERL_MB_OPT=

perl -e "printf("""Perl executable: %%s\nPerl version   : %%vd\n""", $
+^X, $^V)" 2>nul
if ERRORLEVEL==1 echo.&echo FATAL ERROR: 'perl' does not work; check i
+f your strawberry pack is complete!
echo.

Thanks all for comments.
