2-8
Getting Started
TCP/IP Connection Settings
The TCP/IP Telnet Configuration dialog box can be displayed from the Connection
Wizard Host Information dialog box by setting the Connection Type to TCP/IP
then clicking the Advanced button, or the New Connection dialog box when in nonWBT mode by selecting TCP/IP in the Type list box then clicking the Configure
button.
Note that the options available and the default settings depend on the current terminal
emulation.
Host Port Number
This enables you to specify the Telnet port number. The default Telnet port number,
23, can be substituted with any valid 16 bit port number. Specifying a number outside
the valid range will cause the setting to default to 1.
If an SSH (Secure Shell) connection is to be made, set this to the host's SSH port
number (22 is the default for SSH).
Local Port Number
This enables you to specify the local Telnet port number if required. Setting this to 0
will cause the number to be allocated automatically.
Telnet Name
This enables you to override the name that will be reported for the terminal type over
Telnet.
Enable Keep Alives
Selecting this option will prevent the session from being disconnected from the host by
an inactivity timeout.
2-9
Getting Started
Connection Timeout (Secs:)
This enables you to specify how many seconds the emulator has to attempt to make a
host connection before it either attempts to connect to the next host (if Host Rollover
is specified in the Host Connection dialog box) or it issues a Connection Failed message. The default 0 setting will cause the emulator to use the stack default timeout.
Suppress Echo
When selected, this will will prevent the emulator from generating the Telnet echo
option on connection.
Suppress 3270 Regime
When running the IBM 3270 emulation, the setting of this option determines whether
or not support for the Telnet "3270 regime" option is suppressed.
Suppress TN3270E
When running the IBM 3270 emulation, the setting of this option determines whether
or not support of TN3270E is suppressed. When this option is not selected (i.e.
TN3270E is not suppressed), additional options are available by clicking the 3270Options button. These are described in the TN3270 Options section.
Suppress TN5250E
When running the IBM 5250 emulation, the setting of this option determines whether
or not support of TN5250E is suppressed. When this option is not selected (i.e.
TN5250E is not suppressed), additional options are available by clicking the 5250Options button. These are described in the TN5250 Options section.
Force Negotiation
These settings determine whether or not the Telnet Binary or EOR options are supported. Both are set to no by default.
NoWill not force any negotiations. It will leave it up to the
host to decide what to do.
DOWill force negotiation. The host will be informed that the
option is supported.
DONTWill force negotiation. A negotiation packet will be sent
to the host telling it that the option is not supported.
Break Settings
The setting of these options determine whether or not a timing mark (TM) and/or
carriage return (CR) is sent with a Telnet break packet. A timing mark is sent by default.
2-10
Getting Started
Send Location
This enables you to enter the location of this terminal which may be used by the host
to provide a list of users currently logged in giving their name and location.
TN3270 Options
This dialog box is displayed by clicking the 3270 Options button in the TCP/IP
Telnet Configuration dialog box when TN3270 is not suppressed.
Connect
This specifies the name of the device which the server will be requested to assign to the
Telnet session; it may be used when requesting either a terminal or a printer session.
You can return the local host name by entering %s after the device name. To return the
user name, enter %u after the device name. You can specify how many characters of
the name is returned in each case. For example, %.3s will return the first three
characters of the local host name, and %-.3s will return the last three characters.
To automatically assign a new device name for each successive connection, either
enter %dN% after the name, where N is a decimal value, or %xN%, where N is a
hexadecimal value. Each time the host requests the device name a counter will be
substituted into the device name. If the host rejects the device name as in use the
counter will be incremented modulus N and the name retried until all possibilities have
been tried, at which point the emulation will report a device name rejected error.
For example, TEST%d4% will give TEST1 on all connections until the host rejects
the name as in use, in which case TEST2 will be used. If this is already in use then
TEST3 is used, or if already in use then TEST0. These values are preserved over
2-11
Getting Started
power off, so the first connection of any given power on may not be TEST1. Assume
that the start point is random.
Note: There are separate counters for the IBM 3270 and IBM 5250
emulations.
When you achieve a TN3270E connection, the LU device name that you are
connected as will be displayed on the status line. If the specified device is rejected by
the server or host, then an error message box will be displayed indicating the reason.
Associate
This is available when the IBM 3270 Model option is set to 3287-1 (a printer). It is
used to request that the device name of the printer associated with a particular terminal
is assigned to this Telnet session. The name of the terminal is specified here. (This is
implemented as described in RFC 1647.)
TN3270E Options
TN3270E in implemented as described in RFC 1647. These options should not be
changed unless required by your System Administrator.
The Bind setting determines whether or not the server is allowed to send the SNA
Bind image and Unbind notification to the emulator.
When Responses is selected, positive and negative response handling is supported. It
allows the server to reflect to the emulator any and all definite, exception, and no
response requests sent by the host application.
When SysReq is selected, some (or all, depending on the server) of the functions of
the SysReq key will be emulated and the server in an SNA environment.
The LU1 and LU3 Printer options are available when the IBM 3270 Model option is
set to 3287-1 (a printer). They enable you to specify which printer type(s) to support.
2-12
Getting Started
TN5250 Options
This dialog box is displayed by clicking the 5250 Options button in the TCP/IP
Telnet Configuration dialog box when TN5250 is not suppressed and the IBM 5250
Model is not set to 3812-1 or 5553-B01 (printers). Refer to the next section for 5250
Printer Options.
Device Name
This enables you to enter the name of the device which the server will be requested to
assign to this Telnet session.
You can return the local host name by entering %s after the device name. To return the
user name, enter %u after the device name. You can specify how many characters of
the name is returned in each case. For example, %.3s will return the first three
characters of the local host name, and %-.3s will return the last three characters.
To automatically assign a new device name for each successive connection, either
enter %dN% after the name, where N is a decimal value, or %xN%, where N is a
hexadecimal value. Each time the host requests the device name a counter will be
incremented modulus N and substituted into the device name.
For example, TEST%d4% will give TEST1 on first connect, TEST2 on second,
TEST3 on third, TEST0 on fourth, TEST1 on fifth and so on.
TEST%d100% will give TEST1 on first connect, TEST2 on second, ... TEST99 on
99th, TEST0 on 100th, TEST1 on 101st and so on.
These values are preserved over power off, so the first connection of any given power
on may not be TEST1. Assume that the start point is random. In addition there is a
single counter for the unit so concurrent sessions will start from subsequent values. For
example, if session one uses TEST1 then session two will use TEST2.
Where a device name collision occurs (i.e. the device name is already in use on the
host) the host will ask again for the device name during the same connection. In this
2-13
Getting Started
case TEST1, TEST2, ... may all be tried in one connection until the host accepts one,
or all possibilities have been tried. In the latter case the same name is sent twice in
succession to indicate to the host all names have been tried.
If concurrent 5250 sessions are started before a previous session has negotiated an
acceptable device name, it is possible that the two sessions will access the counter
simultaneously and not all possible names will be tried by each session. This should
not cause a problem unless the separate sessions use different modulo values (for
example, session one device name TEST%d4% and session two device name
ANOTHER%d100%) or are connecting to different hosts.
Note: There are separate counters for the IBM 3270 and IBM 5250
emulations.
