[NFBCS] JAWS, PuTTY and caret tracking

Tue Sep 15 12:03:29 UTC 2020

Hi.

The ^C and ^D you are getting are not due to Jaws. I can pretty much garantee you that it is due to the prompt not supporting arrowing, and you would undoubtedly see this same issue with another screen reader, or with no screen reader at all. In short, you can't arrow through the line at the SQL prompt likely because no one can.

As for the rest, have you tried the standard Windows SSH client? I can just open a PowerShell prompt or command prompt, and type "ssh user at host.com" to use it, but you may have to tell Windows to install it first. If Jaws is still unable to determine which item is highlighted in the menu, then at least you'll know that it's not specific to PuTTY. I suspect that such tracking is a much harder problem than simple cursour tracking. 

Good luck.
