[NFBCS] JAWS, PuTTY and caret tracking

Wed Sep 16 02:12:23 UTC 2020

Hi Aaron,

That explains a lot.  Oh well.

I have tried the Win SSH client but it always locks me out unless I use PuTTY or Tera Term, the latter of which does not appear to be terribly accessible.

Thanks for the response.

Regards,

Nathaniel
