History in busybox shell doesn't work

[Praba Rajah]

I press the up key and I expect my previous command , but instead I see nothing. 
  The command prompt is empty. 
   
  All three terminals are sent same char sequences. Up arrow is same as you.
   
  $ ./busybox hexdump -vC
^[[A (<-- when I press "up arrow" and then ctrl-D several times)
00000000 1b 5b 41 |.[A|
00000003

   
  # busybox hexdump -vC
  ^[[B (<-- When I press "down arrow" and then ctrl-D)

  00000000 1b 5b 42                                                             |.[B|
  00000003
   
  When I type "history" in the debug port command prompt I am getting: 

  # history
sh: history: not found

   
  But when I type in the telnet terminal or Serial port terminal I am getting 
   
  # history
-ash: history: not found

   
  Also I have noticed -ash process started after telnet / serial port connection were made.
   
  We are using different .config files for each versions. Version 1.7.2 .config file which doesn't work is attached here. Please have a look.
   
  Thank you for your reply.

Perhaps you can be more specific. Describe how do you use history
("I press key X and I expect A to happen, but instead I see B").

Let me know what char sequences are sent by up/down keys
on both "good" and "bad" terminals.

For example, on this machine I can find it out as follows:

$ ./busybox hexdump -vC
^[[A (<-- I press "up arrow" and then ctrl-D several times)
00000000 1b 5b 41 |.[A|
00000003

So, on this terminal "up arrow" is ESC [ A.

Does it happen with the same .config on a x86 desktop/laptop?
Can you post your .config?
