600 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
28 Programming Fundamentals
You need to press Enter after typing in each command. After pressing Enter on the last line
in the example above, the instrument returns the amplitude level of the marker to your
computer and displays it on the next line. For example, after typing (for N8201A)
CALC:MARK:MAX? and pressing Enter, the computer could display:
+2.50000000000E+010
When you are done, close the telnet connection. Enter the escape character to get the
telnet prompt. The escape character (Ctrl and "]" in this example) does not print.
At the telnet prompt, type quit or close.
The telnet connection closes and you see your regular prompt.
Connection closed.
The following example shows a terminal screen using the proceeding example commands.
Telnet Example:

If your telnet connection is in a mode called “line-by-line,” there is no local echo. This
means you will not be able to see the characters you are typing on your computer's display
until after you press the Enter key.
To remedy this, you need to change your telnet connection to “character-by-character”
mode. This can be accomplished in most systems by escaping out of telnet to the telnet>
prompt and then typing mode char. If this does not work, consult your telnet program's
documentation for how to change to “character-by-character” mode.
The Standard UNIX TELNET Command:
Synopsis telnet [host [port]]
Description The telnet command is used to communicate with another host using the
TELNET protocol. When telnet is invoked with host or port arguments, a connection is
opened to host, and input is sent from the user to host.
