Booting the PortServer Software with Remote Boot

A feature of the PortServer operating system software is that it can be upgraded without ROM
or other hardware changes. Any upgraded software from Digi can be installed on a host on the
network that supports TFTP (Trivial File Transfer Protocol).
First, configure the PortServer box for remote boot by using
set config boothost=
to specify the ip address of the host with the upgraded software on it.
Next, configure the PortServer for the filename of that software with
set config bootfile=
(Make sure that filename includes the complete path.)
Reset the PortServer unit by turning its power switch off, then on again. The PortServer
firmware will then go through its self-testing, then load its operating system software from the
specified host.
