IP Host Name
This is the name, or IP address, of the host computer to connect to. If
a text string is entered the TCP/IP protocol will translate it into an
IP address. The IP address number can also be entered directly.
Both IPv4 and IPv6 are supported.
TCP Port
The default value for this parameter is 23. Normally, this number is only
changed for security purposes.
Timeout (sec)
This value designates the number of seconds to wait for a host connection.
If a connection is not made within this time period and there are alternate
back-up IP Host Names configured in the Advanced tab,
then an attempt to connect to those IP Host Names will be made.
Auto Reconnect
If this option is enabled, PASSPORT will try to reestablish a session with
the host if that session times out or is unexpectedly disconnected or
if the host is down when trying to connect. PASSPORT will attempt to reconnect
after first waiting for 1 second, then 5, 10, 15, 20, 25 seconds, and
then 30 seconds thereafter between each attempt until a connection is
established. This helps reduce network traffic. Once PASSPORT successfully
connects to the host, the reconnection value will be reset to 1 second
again.
If you log off a mainframe session using a command such as VMEXIT, LOGOFF,
or CSSF LOGOFF, the host session will be disconnected and another session
with the host will automatically be initiated, returning you to the host
log on prompt. If this option is not selected, you will get a blank
screen if disconnected from your mainframe session. You will then have
to perform a Communication>Disconnect
command followed by a Communication>Connect
command to reestablish the session.
Screen Size
For TN3270 emulation, screen size models 2, 3, 4, 5, and Dynamic are supported.
The model number refers to the number of rows and columns the terminal
can display. If you do not configure the correct screen size, you may
not be able to make a connection to the host.
Model 2 (24 rows x 80 columns)
Model 3 (32 rows x 80 columns)
Model 4 (43 rows x 80 columns)
Model 5 (27 rows x 132 columns)
Dynamic
Rows
For custom screen sizes, this sets the number of rows to display. Enter
an integer between 24 and 125.
Columns
For custom screen sizes, this sets the number of columns to display.
Enter an integer between 80 and 255.
Telnet Device
Type Override
This text entry provides the ability to override the Device Type String
that is automatically generated by the Screen Size and Extended Attribute
settings. For
example: If screen size Model 5 and extended attributes are enabled, the
device type "IBM-3278-5-E" is generated in accordance with the
IETF RFC 2355 specifications. However, some older TN3270 servers may interpret
this incorrectly as no extended attributes and may need the device type
"IBM-3279-5-E" typed into the Telnet Device Type Override field.
Host Code Page
Select the appropriate host code page that is used by the host computer
system. This selection determines the translation tables used to convert
text characters between the host and the PC. The default is 1140 for US/Canada
with Euro support.
TN3270E Support
If this option is enabled, TN3270E enhanced terminal emulation is used
and the following features are supported. If the host computer does not
support TN3270E and this option is enabled, then basic TN3270 will be
used.
TN3270 Attention and System Request key support
Support for connection to specific LUs, associated
LUs, and LU pools
(LU is an abbreviation for Logical Unit)
IBM 3287 LU1 and LU3 host printing support
SSCP-LU session support
SNA BIND and UNBIND support
SNA-like response support
Generic
This is the default TN3270E connection method. The session established
with the TN3270 server comes from an unnamed pool of LU's. The unnamed
pool is identified by the 3270 screen size and extended attribute settings.
For example, if you configure a 3270 model 2 screen size without extended
attributes, the session will be established with an unnamed pool of LU's
having the device type IBM-3278-2.
Specific
This connection allows connections to a specific name LU pool, or to a
specific dedicated LU. A dedicated LU is basically an LU pool with a single
LU in the pool. If you select the Specific
option, you must also enter the Resource Name that corresponds to the
name of the dedicated LU or LU pool.
Resource
Name
This is the device or pool name used by PASSPORT and the TN3270E server
to identify and establish a connection to a specific LU or LU pool. Your
system administrator must give you the correct information to enter here.
Extended
Attributes
This configuration option determines whether or not extended attributes
will be displayed. Extended attributes includes seven-color display, underline
and reverse video. Enable the Extended Attributes check box to enable
these features.
TN3270E
Response Support
This option determines whether or not TN3270E Responses are supported during
TN3270E terminal emulation. For TN3270E display sessions this setting
is usually off.
TN3270
Non-SNA Command Chaining
Enable this option if connecting through a Visara controller. The Visara
controller requires the TN3270 client to do the 3270 command chaining
required by Non-SNA Master Console operation. If not connecting through
a Visara controller, this option should be disabled.
Scroll
Back Buffer (n) Lines
This option allows you to activate the history log which stores data (in
lines) that are no longer displayed on the screen. You can then
use the scroll bar on the right side of the PASSPORT window to scroll
back and view previous host screens. The default number of lines in the
history log is 24. However, you can increase this log to a maximum of
2000 lines.
