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) 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.
