Description

bcmsh does not support up/down arrow, backspace or history.

This made it not useful for interactive shell.

To fix this, we need upgrade socat so it supports READLINE feature and we should pass READLINE parameter when calling from socat to UNIX socket.

Steps to reproduce the issue:
1.
drivshell>^[[A
-- up arrow case.

drivshell>^[[B

--- down arrow case

drivshell>l3 nat^H

-- backspace case
