If you just need a resizeable terminal to run Perl in, you could always use Cygwin's mintty or ConEmu.

ConEmu did the trick, combined with pryrt++'s plink idea. It took a little configuration to make it look like a boring console window again, mainly invoking cmd.exe without parameters, using the default windows color scheme, and hiding the status bar and the tab bar.

Thank you!

And now that perl is involved, and ConEmu supports ANSI, I already consider using ANSI sequences to highlight matching lines instead of filtering out all irrelevant lines ...

Getting rid of unwanted lines:

plink -serial COM24 -sercfg 115200,8,n,1,N | perl -ne "/^(Pct|NRS)/ &&
+ print"

Highlighting interesting lines instead:

plink -serial COM24 -sercfg 115200,8,n,1,N | perl -MTerm::ANSIColor -n
+e "print colored($_, /^(Pct|NRS)/ ? 'bright_yellow' : 'white')"
