E Communicating Through
TCP/IP over Telnet
Introducing TCP/IP over Telnet
The EXFO Instrument Control provides SCPI automation or remote control
over Telnet through TCP/IP as a Windows Service that continuously listens
to a port from a Telnet server (FTB/IQS/LTB) on which modules to be
tested are connected.
TCP/IP protocols are used for communication.
Note: Port 5024 is designated for sending SCPI commands in the Telnet protocol.
All Windows versions include the Telnet client and the Telnet server
components. With these components, you can create a remote command
console session on a remote computer.
Commands can be executed simply by logging on the server using the
Telnet interface.
There are two types of commands that can be sent over Telnet: SCPI
commands and internal protocol commands of the TCP/IP over Telnet
service. The internal commands allow you to perform certain actions such
as send SCPI commands as a script instead of one by one, force the
disconnection of an active session, view the status of modules and of
connected clients, etc.
