How do I make linux console act EXACTLY like sco console?

1. What tool allows Linux to act as a terminal console?

Sorry if this sounds dumb, but I'm not a Linux expert.

I have a Sun netra server that I need to connect to
using a terminal console via the netra's serial port.
I usually connect to it using a comm port on a lap top
that has Tera Term Pro installed, and using a null
modem cable that connects to the serial port of the
netra.  Once I make all the correct settings (BAUD rate,
Port connections etc...) I can use the lap top as a
terminal console.  Is there any way of doing this
on a Linux box?  Tera term pro does not have a linux

Thanks in advance,
