[Blind-sysadmins] Question about using JFW with putty

Hi, so here's the issue. I use putty as an SSH client. In order for me to hear the output I have to do an insert s to speak all. This works but when the screen fills it rereads the entire screen over and over again for each new line added. What's up with that? Secure CRT has a script written that gets around this. What can I do to use putty or is there a better (preferably free) client to use that's more jaws friendly? Any pointers would be appreciated. Thanks Scott
