2. Click the Terminal tab.
3. When you are connected to a device that does not repeat or echo the data that you type, you
may enable Local Echo mode. Otherwise, the Telnet Viewer will not display the text you type.
However, if you are connected to a device that echoes data, and you are in Local Echo mode,
all of the data you type will appear on your terminal twice.
Enable or disable the Local echo checkbox. The default value is disabled.
To enable/disable 7-bit ASCII:

3. Enable or disable the Strip 8th bit checkbox. The default value is disabled.
Login scripts
The Telnet Viewer has a login scripting function that enables you to automatically log in to a
device. A login script is built with a sequence of expect and send strings, and initial transmission
characters that work with them. To use a login script, you must enable automatic login in
a checkbox.
The first Initial character (that is, the first entry in the Initial character column) specifies what is
sent to the device as soon as the Telnet Viewer session is established. This is selected from a list
containing the choices: None, CR (carriage return), CR+LF (carriage return and linefeed), ESC
(Escape) and CTRL+P (Control and P).
The first Expect string indicates what the device will send as its first prompt.
The first Send string indicates what the login script will send to the device after it receives the first
Expect string.
You may then build additional Expect and Send strings according to what the particular device will
prompt for and what will be sent in response.
To build a login script and enable/disable automatic login:
1. Select Options - Session Properties from the menu or click the Session Settings icon in the
toolbar. The Session Properties dialog box will appear.
2. Click the Login Scripts tab.
3. Enable or disable the Automate login checkbox. The default value is disabled.
4. In the Initial Character list, select one option: CR (carriage return), CR+LF (carriage return and
linefeed), ESC (Escape), CTRL+P (P sequence, 0X10 in hex) or None (no initial
transmission character).
5. In the Expect box, type the 1-32 alphanumeric character string that you expect from the device.
Spaces are allowed.
