Managers,

        I had originally asked these questions:

> 1. When logging on, you cannot use the delete key to fix
> a typo in your username? Does anyone know how to fix this? It
> just appends '^?' to the string of text.
>
> 2. Using lynx, when I select D to download, then you are prompted
> to save your file to whatever you like, when any character is
> pressed, the cursor move to the next line as if a carriage
> return was entered. The backspace does not work here either.
>
> Are these (and maybe the next one too) problems related or are
> they all separate problems?
>
> also: In ksh, how do you recall your last commands, when the arrow
> keys are pressed, '^[[A' is used. How do I use the history
> to recall my commands?


These are the people that responded and their responses. Sorry if I left
any out.

I have run into something similar to this, but only when telnetting from
an Ultrix host into my Alpha and then running the Alpha's Lynx client. I
find that using rlogin to go from the Ultrix machine to the Alpha avoided
these problems.

In reference to ksh question, put
set -o emacs
in yout .profile file

No these problems are not *necessarily* related (e.g. I have
problem 1 but not the rest). The rest, now: your lynx
problem may by termcap related. The ksh problem is solvable
and also termcap related. The first problem has as solution
to use Ctrl-H to backspace-delete the erroneous characters
*in your login*; beware that the password line may not
use the Ctrl-H anymore but the "usual" delete key.

          There are two keys on the keyboard. Backspace and Delete.
          According to the POSIX spec backspace = ^H and delete = ^?
          (^? represents the non-printing number 127).
          In order to comply with POSIX, the line discipline for
          telnet and rlogin etc. is set to be POSIX (stty sane).
          Unfortunately, by default, DEC keyboards generate
          ^? when the backspace key is pressed. IBM keyboards generate
          a ^H when backspace is pressed.

          As an experiment try pressing ^H (Control-H) at the
          login prompt. Also since the requirement for posix compatibilty
          does not extend to LAT, you can 'delete normally' for a LAT
          connection. Standards - wonderful things.

          If it really bugs you, you can switch this off, by
          changing the line discipline on /etc/gettydefs. At the
          normal shell prompt 'stty sane' swaps to POSIX mode. and
          'stty dec' swaps to 'normal' dec mode.
