No handshake
A null modem configuration is needed, meaning the transmit and receive signals are
reversed (crossed over) for DTE to DTE communications. You can use the supplied
RJ-45 crossover adapters with a standard RJ-45 cable to achieve the null modem

Note When you power on the server for the first time and you do not have a
terminal or terminal emulator (PC or workstation) connected to the service processor
serial management port, you will not see system messages.
