Need a null modem cable/adapter.  I use a 9pin-RJ45 null modem
adapter and then I carry 9 and 25pin to RJ45 adapters for use
with the servers.   Of course, I really don't have a 9pin
serial on my laptop, so actually I use a USB to 9pin adapter
to get a serial port (9pin serial now considered to be obsolete
legacy stuff).  By using RJ45.. I can just string a piece of
CAT5 (network cable) of any length to connect.

Then use minicom to access.  I usually set for 9600 8-N-1, seems
to be work with the normal default for most devices (server, routers,
switches, etc).  You may have to adjust those values based on
the server's needs.
