NXB-KNX Operation/Reference Guide
Appendix A: Telnet Commands
Overview
The NXB-KNX supports Telnet communications. This type of terminal communication can be accessed
remotely, via TCP/IP.
Telnet is an insecure form of terminal communication, since it does not require a physical connection to the
device to connect. Further, the Telnet interface exposes information to the network (which could be intercepted
by an unauthorized network client).
Refer to the
Terminal Commands
section on page 52 for a listing of all commands available in a terminal
session.
