Using the Command Line Interface
The next two sections show how to connect to the ptf 3207A using the serial and Ethernet (telnet)
ports. Both the serial port and the telnet interface give the user access to the ptf 3207A’s command
line interface. While the keypad/display interface provides a simple menu-driven user interface, the
command line interface features:
• Additional functions that aren’t available through the keypad/display
• Remote access over a network
To use the command line interface, refer to the explanations and examples in the ‘Command Line’
subsections for each function in the ptf 3207A User’s Guide and Reference Manual.
Connecting to the Serial Port
Complete the following steps to set up and use the Serial Port to communicate with the XLi.
Set up the required baud rate as described in the" Configuring the Serial Monitor/Control Port" section
above.
Connect a null-modem cable from the PC’s serial port to the ptf 3207A’s DB9 connector.
If needed, configure your PC’s terminal emulation program (e.g. Hyperterminal) to match the serial
port settings above (57600, 8, N, 1). Set Hardware Flow Control to “None”.
Initiate a serial port connection between the terminal emulation program and the ptf 3207A. (The
Serial Port connection does not require you to log in.)
Once connected, press ? followed by the Enter key on your keyboard to display the standard menu
commands.
To display the extended help commands type:
showptf<ENTER>
Tip: If the terminal emulation software has trouble communicating, verify the serial port settings.
