Communicating Through TCP/IP over Telnet
FTB-2 and FTB-2 Pro 415
Internal Commands of the TCP/IP over Telnet Protocol
Internal Commands of the TCP/IP over Telnet
Protocol
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. The internal commands are not case-sensitive.
By default, log files are generated both for client and server (all logs are
kept on your unit). You can delete them with the CLEAR LOGS command
(see CLEAR LOGS on page 417), or manually via the file explorer. The client
and sever logs are kept respectively in the C:\ProgramData\EXFO\SCPI
Over TCPIP Logs\Client log and in the C:\ProgramData\EXFO\SCPI Over
TCPIP Logs\Server log folders.
ABORT BEGIN
Syntax: ABORT BEGIN
The ABORT BEGIN command stops the execution of the SCPI commands
that are enclosed in a BEGIN and END block, and returns to the READY>
prompt in the Telnet editor window.
