Bug Description

I support a number of systems remotely, and often find myself using vi in an ssh session to edit various files. In some cases, but not all, when I press the up arrow (in insert mode) I get a capital letter A and a new line instead of the cursor moving up. Other arrow keys have similar issues. This only seems to be a problem when in insert mode.

My system is 12.04 64 bit. When I connect to a remote system that is 64 bit it works fine, but when I connect to a remote 32 bit system, I have the described problem.

Hi Mitch. Thats very interesting, and thank you for taking the time to file a bug report.

Can you please paste the output of 'ssh -vv ...' to one of the problem systems? Also if could you share what terminal you are running in (such as konsole, Terminator, putty, the raw virtual terminals, etc.) and the value of $TERM? Thanks.

More info: it is not 32 bit systems with which I have a problem, but systems that only have vim-tiny and not vim. The systems I was having trouble with are desktop systems which only install vim-tiny by default. Installing vim fixed it, for both 32 and 64 bit systems.
