Sending keys with escape sequence e.g up key appears as ^[[A in terminal

[Vinode Singh Ujlain]

I am new to the group adn was searching if my question has been addressed prior , didn't find any. Please look at the below code (a simple ssh client connected to ssh server ). Commands fired work interactively , however when a escape key is pressed , it appears as it is example up key when pressed appears as ^[[A , it should ideally get an item from history. How do I correct this ? or rather , this is a problem with every ssh client I tried , how do I handle keys with escape sequence ?
