It looks like you're out of luck. The Term::ANSIColor docs note that blink is often not available depending on your terminal. The Win32::Console::ANSI which is trying to emulate terminal handling for your Win32 console, notes that blink mode is not implemented. In the old days we'd use ANSI.SYS (or a better clone) to do decent ANSI/VT100 escape sequence control, but that isn't an option under Win2k/XP's CMS.EXE it would seem.

Perhaps you can find a better Win32 console shell?
I'd like to be able to assign to an luser
