Issue with 'Backspace' and 'Delete' Keys [17]

Am using Xshell 3.0 on Vista Ent. When connected to a AIX host the 'Backspace' and 'Delete' Keys doesn't work as desired.

But for the same putty work pretty fine. Tried all the options in Terminal > Keyboard, none of them helped.

Putty config and the xshell build screenshots attached.


Program Ver. : Xshell 3.0

Delete doesn't work in most shell environment. You can try this on console. I have tried with Putty too but the delete doesn't work there either.

However, backspace key works if the backspace option is set as 'Backspace (Ctrl+H)' in Properties > > Terminal > Keyboard.

It does delete but the text shows up as it is... check the attached screenshot for a clear idea...

Thank you for using Xshell.

We have tested on AIX 5.3 but the problem did not occur.

Please try de-selecting the 'Insert Mode (IRM)' option in Terminal > VT mode.

Also, if your problem persists, please send us the following information:

1. Terminal Type
2. Language

Thank you.

Problem remains the same.
Screenshots attached.

For terminal and language encoding type, please send us the outputs of the following commands:

In terminal screen, give

1. For terminal type: echo $TERM
2. For language setting: echo $LANG

Thank you.

$ echo $LANG
en_US

$ echo $TERM
xterm

This problem can occur when echo is turned off in ksh. Try giving the following command:

$ stty echoe

Hope this helps.

Doesn't work either...

This problem could not be duplicated. Since we are testing this on a same AIX machine, I am almost certain that this is probably a configuration problem. Please post the result of 'stty -a'

Also, could you confirm that backspace functions as normal in Putty?

It would help us solving this problem if you can provide us with a test account on the AIX machine. If you can, please send us the account and server information to support@netsarang.com.

Yes, Backspace works fine in Putty.

THIS HAS TO BE FIXED ASAP...

Now, I have found another AIX box where for root user the Backspace works pretty fine but it doesn't work for other users...

You must enable echoe and echoctl values. You can do this by using the following commands:

stty echoe
stty echoctl

I tried adding the following to the user's .profile. It works for the current session, even works for the session with "su", but no help when we switch user with it's environment "su -".

$ tail -3 .profile
stty echoe
stty echoctl
stty erase ^H


If i have to enable echoe and echoctl values to make the Backspace to work as desired, how come a free client like putty currently working fine? Hence I won't be able to add the 'echoe and echoctl' to the global profile file.

Our developers are working on this and we will release a patch for this feature in the near future. I will let you know the earliest when the patch is released.

Thank you for your patience.

This feature has been added in the latest release. You can download it at:

This option, ?Destructive backspace?, can be found in Terminal > Advanced in the session properties. Please make sure to set the backspace key as ?ASCII 127 (Ctrl+?)?.
