Console tool advice

[Kris]

Hey group,
 I have successfully transformed my Dell laptop into a smokin linux
boxen, everything my company does I can do in linux(and better).
There is one thing I do that I need advice on. To trouble shoot some
network issues sometimes I have to console into routers or switches with
the serial port on my laptop, in win$ I just use hyperterminal. What do
people use to do this in Linux? This is probably something Very simple
but I have just never came across it or can't find the experiance online.

 -Thanks
