provisioning
The process of configuring a mobile (cellular) device with the required configuration

RealPort
RealPort is patented Digi software for COM port redirection. RealPort makes it possible
to establish a connection between the host and networked serial devices by creating a
local COM or TTY port on the host.
The COM/TTY port appears and behaves as
a local port to the PC or server.
This process of COM port redirection allows
existing software applications like DNP3 and Modbus to work without modification.
Unlike other COM port redirectors, RealPort offers full hardware and software flow
control, as well as tunable latency and throughput. These features ensure optimum
performance, since data transfer is adjusted according to specific application
requirements.
remote login (rlogin)
A remote login to a Digi device’s command-line interface (CLI). rlogin is a Unix
command that allows an authorized user to login to other UNIX machines (hosts) on a
network and to interact as if the user were physically at the host computer. Once logged
in to the host, the user can do anything that the host has given permission for, such as
read, edit, or delete files.
remote shell (rsh)
A Berkeley Unix networking command to execute a given command on a remote host,
passing it input and receiving its output. Rsh communicates with a daemon on the
remote host.

router
In Mesh/ZigBee networks, a router is a node that creates/maintains network information
and uses this information to determine the best route for a data packet. A router must
join a network before it can allow other routers and end devices to join to it. A router
can participate in routing packets and is intended to be a mains-powered node.
Characteristics of routers include:
– Several routers can operate in one PAN
