Router Configuration Under Linux ?

I know how to configure a Router through the Hyperterminal in Windows but i am not able to get a same variant in Linux.

Some body told me MiniCom is the replacement for the Hyperterminal but i am not able to configure the Minicom stuff.

I searched for many help sections on the net but no solutions yet. So, if anybody have solved this problem practically than please help me out.

So please send me some relevant inf on the same.
