Remote Command Interface (RCI)
A programmatic interface for configuring and controlling Connect family devices. RCI is an
XML-based request/response protocol that allows a caller to query and modify device
configurations, access statistics, reboot the device, and reset the device to factory defaults.
Unlike other configuration interfaces that are designed for a user, such as the command-line or
browser interfaces, RCI is designed to be used by a program. A typical use of RCI is in a Java
applet that can be stored on the Connect device to replace the browse interface with a custom
browser interface. Another example is a custom application running on a PC that monitors and
controls an installation of many Connect devices.
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.
rlogin

RTS

RXD
Receiving Data.
Secure Sockets Layer (SSL)
A commonly-used protocol for managing the security of a message transmission on the Internet.
SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL.
serial bridge
A connection between two serial devices over a network that acts as if they were connected over
a serial cable. Also known as serial tunneling.

Short Message Service (SMS)
A technology that enables the sending and receiving of messages between mobile devices. The
data that can be held by an SMS message is very limited. One SMS message can contain at most
140 bytes (1120 bits) of data, or up to 160 characters if 7-bit character encoding is used, and up
to 70 characters if 16-bit Unicode UCS2 character encoding is used.
