Fullscreen={ no, yes}

Default is no.

Yes/no option to run the session in full screen. If Fullscreen=no then the session runs in a windowed screen.

Host=[name, IP, $SYS VAR]

or

Application=published application

Host — A list of server hostnames or IP addresses to which the thin client will attempt to connect. The next server on the list is attempted if the previous one failed. List items must be separated by semicolons or commas.

  • NOTE:

    $UN (see Table 1) specifies that the sign-on user name is used and should be set in a {username}.ini file. If set to Host=$UN in a {username}.ini file, the hostname will display as the sign-on user name. If set to Host=$UN in a wnos.ini file, the hostname will display as the default start.

Application — Defines the published application to launch. Application is required if no host is specified.

HttpBrowsing={ no, yes}

Default is no.

Yes/no option to select an http browsing protocol. Use HttpBrowsing=no for User Datagram Protocol (UDP).

Specifies an icon to appear on the thin client desktop for a connection. Use Icon=default to display a system default icon for a connection.

To use an icon other than the default icon, enter the name with extension of the bitmap file; ensure that the file is located in the FTP server wnos\bitmap directory. If Icon= is not specified and the icon is not specified by a PNAgent/PNLite server, no icon is displayed for a connection.

KeepAlive={0 to 127}

Specifies the number of minutes to keep a session connected after the session is inactive. During this period, one dummy packet will be sent to the server if network traffic is lost. Default is 10.

LocalCopy={ no, yes}

Default is no.

Yes/no option to save the connection to the local NVRAM.

The connection description of the Description option is used as the index key into the local connection table. If a match is found, then the entry is updated. Otherwise, a new entry is created.

Logon_mode={ local-user, smartcard, user-specified}

Default is local-user.

Specifies how users authenticate to the selected application set or ICA connection.

Lowband={ no, yes}

[NO_FontSmoothing={ no, yes}]

Default is no.—font smoothing is enabled by default.

Yes/no option to disable font smoothing. If set to yes, the font smoothing is disabled.

NoReducer={ no, yes}

Default is no.

Yes/no option to turn off compression. Default is no, which enables compression. To turn off compression, enter yes.

Used here is an option of the Connect statement. It sets the value of NoReducer only for this specified connection.

  • NOTE:

    By default the ICA protocol compresses the data to minimize the amount of data that needs to traverse the network. This compression can be as much as 50 percent for text-based applications such as Microsoft Word and 40 percent less for graphics applications than the data streams that are not compressed.

Password={password, $SYS_VAR}

Password to log-in to the application server. Either a conventional login password or a variable can be used. Maximum of 19 characters are allowed.

The value of password is a conventional login password.

The value of $SYS_VAR is a system variable found in Table: System variables.

  • IMPORTANT:

    The application server password is not encrypted; it is strongly recommended not to specify it. The user will be prompted to enter the password when the connection is made. This application server password directive never starts a line, so it can be distinguished from the thin client user sign-on password which does starts a line.

  • NOTE:

    The Password option is not written into a {username}.ini file by a user. When the New Password check box is selected, the system writes the new, changed password into the {username}.ini file with encryption. This password is then checked against the sign-on password with encryption to determine whether sign-on is successful.

Password-enc=an encrypted password Specifies an encrypted string as a password for a connection.

Reconnect={ no, yes, 1 to 3600 (seconds)}

Default is no.

Controls automatic reconnection to an application after a server disconnection.

yes — Use to restart the connection; the default delay time for yes reconnect is 20 seconds.

no — Use to prevent reconnection after a disconnect.

1 to 3600 — Use an integer value of 1 to 3600 seconds to restart the connection after the delay you want. For example, use 50 and the automatic reconnection to an application will occur after 50 seconds.

Resolution=[ default, Seamless, <monitor resolution>]

Default is default.

Specifies the connection display resolution.

default — Starts the connection using the current desktop display setting with no window frame and border.

Seamless — Available for use if the connection is to a published application. For Seamless connections, the MetaFrame hosts select the best-fit connection window for applications.

<monitor resolution> — Resolution values you can use in the form X x Y depending on your client. Example for monitor resolution: 1024 x 768. See the Release Notes of your client.

SessionReliability={ no, yes}

Default is no.

Yes/no option to enable session reliability.

  • NOTE:

    ThinOS thin clients do not support UDP browsing to obtain a new configuration about session reliability on the server. The thin client always connects to the default port.

UniSession={ no, yes}

Default is no.

Yes/no option to use a unisession. The connection will launch only once at a time.

UnmapClipboard={ no, yes}

The value of $SYS_VAR is a system variable found in Table 1: System variables.

  • NOTE:

    The combination of all the variables such as $IP@$DN are also supported.
