$ I type this line, and then I'll backspace to the comma.

$ I type this line,

TERM=vt100

No clue why yours isn't working.

What's your TERM set to?

[vikas5914]

No idea . how to set TERM ?

Update : i set my TEMR to vt100 . still giving same error and error alert sound

Digging a bit more, I see that plink is little more than a command line putty. But it also appears that the terminal isn't even vt100, since if I enter a man or a clear command, I get ANSI control characters and not actually anything acting on those ANSI control characters. In putty, clear clears the screen. Under ssh, I get

$ clear
←[H←[J

Actually, looking at what your original output is, it's showing an ESC [ for each time that you hit the backspace. Which sounds like it may actually be doing the backspace, but since the console isn't actually processing ANSI/xterm, it's just not displaying correctly.

I thought stty might have something to do with it, but I don't see it. You might want to try a stty sane, just in case.

What happens when you use putty instead of ssh (using port 22 and ssh connection)? And it may be a shell issue. I'm running ksh as my default. Loading sh and zsh, I see problems in trying to use the backspace key. bash and ksh work just fine. Which still may point to a configuration issue with the two (or more?) nonworking shells.

You might be better off just using putty for interactive, and ssh for automated stuff.

And now, zsh is working for me, now that I logged off and back on. :/
