Installation Questions and Answers


What causes "An error occurred during the move data process -113" during installation?

This error comes from InstallShield which we use to package our product. This message may appear when other applications are running while you are installing TN3270 Plus. You must close all other applications prior to installing TN3270 Plus. Close all other applications and try the install again.

If closing all other applications fails, the circumvention is to unzip the TN3270 Plus self-extracting  file using a zip utility. Unzip the TN3270 Plus self-extracting file to a temporary folder and then execute the setup.exe program to start the installation wizard.

If this does not work for you, please send an e-mail to support@sdisw.com or fill out the Quick Contact Form. Please include your telephone number.

License Code Questions and Answers


The license code is not valid for this release.

The license code you entered is for an older release of TN3270 Plus. The license code is generated for a specific release and will not function with newer releases of TN3270 Plus.

The product release level is three digits separated by periods, for example, 3.4.0. The license code only checks the first two digits, so a license code created for 3.4.0 will work with releases 3.4.0 through 3.4.9. In addition, license codes for release 3.3 and above will work with the next higher release. For example, a release 3.4 license code will also work with release 3.5 (3.5.0 - 3.5.9). However, if you try to use a release 3.4 license code with release 3.6.0 or higher you will get the above error message.

If you have purchased a maintenance and support subscription, updates are free. Send an e-mail to sales@sdisw.com with your current "licensed to" name and the new release level and you will be e-mailed a license code for the new release.

If you do not have a maintenance and support subscription, you will need to subscribe to our maintenance and support plan in order to receive the new product release.

Common Connection Questions and Answers


Can I connect to another PC running Windows?

Yes, it is possible use telnet to connect a Windows system to another Windows system and gain access to the command line. It is not possible to gain access to the Windows GUI. The requirements are as follows.

  1. Both computers must be connected to the Internet or on the same network.
  2. The computer you wish to connect to must be running a telnet server. Windows XP Professional and Windows 2000 Professional come with telnet servers. Use the following instruction to start the telnet server:
    Windows XP Professional Start, Control Panel, Administrative Services, Services, Double click on the Telnet service, on the General Tab specify the Startup type and then start the service.
    Windows 2000 Professional Start, Settings, Control Panel, Administrative Tools, Services, Double click on the Telnet service, on the General Tab specify the Startup type and then start the service.

    If the PC is running another version of Windows, you will have to purchase a telnet server application to run on the PC.
  3. You must turn off NTLM authentication on the Windows system running the telnet server because TN3270 Plus does not support NTLM authentication. 
    Windows XP Professional (Open a command prompt and enter tlntadmn config sec=-ntlm)
    Windows 2000 Professional (Open a command prompt and enter
    tlntadmn
    3    *Display/change registry settings
    7    *NTLM

  4. Connect TN3270 Plus. You need the IP address of the Windows PC running the telnet server. Use port 23 and terminal type VT100. You will be prompted for a username and password. The username and password must be defined on the Windows PC you are connecting to. 

(Return to index.)


How do I enter a telephone number into TN3270 Plus?

You cannot enter a telephone number into TN3270 Plus. TN3270 Plus does not support a direct dial connection to a host computer. TN3270 Plus connects to a host computer via TCP/IP using the Internet or an intranet as the communication link. As an example, SDI employees use TN3270 Plus to connect via the Internet to our IBM zSeries (mainframe). To connect:

  1. The user establishes an Internet connection through their ISP.
  2. Starts TN3270 Plus and enters the IP address of the mainframe in the Connect to Host dialog box and clicks the Connect button.
  3. The connection is made across the Internet to TCP/IP running on the mainframe.

Host www.xxx.yyy.zzz Is Unreachable

This message is normally caused by one of the following:

  1. You are not connected to the Internet. You must make your connection to the internet before using TN3270 Plus to connect to a host computer. If you are an America Online (AOL) user, you must connect to AOL and login before trying to connect using TN3270 Plus.
  2. There is a problem on the Internet and currently there is no route to the host computer. Try again later.
  3. If the IP address in the message is incorrect, then you have the wrong "Host Name:" in the TN3270 Plus "Connect to Host" dialog box.
  4. You have the incorrect port number specified in the "Connect to Host" dialog box.

(Return to index.)


Socket error 0 (WSAEUNDEFINED)

Host www.xxx.yyy.zzz port nnn Is Unreachable: Socket error 0 (WSAEUNDEFINED)

You are attempting to connect to an Internet host address and your computer is not connected to the Internet. 

(Return to index.)


Socket error 10022 (WSAEINVAL)

Host hostname port nnn Is Unreachable: Socket error 10022: WSAEINVAL

This error is normally caused by one of the following:

  1. The hostname specified in the Host Name edit box of the Connect to Host dialog box (Host, Connect...) is not valid. 

    The Host Name should be the dotted IP address or the DNS name of the host computer. Every computer on the Internet has an IP address that looks something like this "128.228.1.20". To make this address easier to remember, the IP address may be registered and assigned a DNS name. For example, acmecomputer.com. When someone tries to connect to acmecomputer.com a DNS server on the Internet translates that to 128.228.1.20. In this example, either acmecomputer.com or 128.228.1.20 could be used as the host name.

    Think of the host name as the address of the host computer. It tells TN3270 Plus where the host computer is. You need to find out what the host name or IP address is for the computer you want to connect to. Try talking to the network administrator at the host computer site if you are unsure.

  2. On an intranet (internal network), you may need to make an entry in the Windows "hosts" file to equate the hostname to the IP address.

    You will find the Windows hosts file here:
    Windows 7 c:\windows\system32\drivers\etc\hosts
    Windows Vista c:\windows\system32\drivers\etc\hosts
    Windows XP c:\windows\system32\drivers\etc\hosts
    Windows 2000 c:\winnt\system32\drivers\etc\hosts

    This file should contain an entry that looks something like this.

    192.168.1.5 hostname

    Where:

    hostname    is the hostname from the error message.
    192.168.1.5 is the IP address of the host on your network.

(Return to index.)


Socket Error 10051 (WSAENETUNREACH)

Session x (hostname:port) Socket Error 10051 (WSAENETUNREACH). A socket operation was attempted to an unreachable socket.

This usually means TN3270 Plus cannot find a route to reach the remote host.

This error is normally caused by an incorrect IP address in the "Host Name" edit box in the "Connect to Host" dialog box.

Try pinging the host computer to see if it is responding. You can this from the Windows command prompt (Start, All Programs, Accessories, Command Prompt) by entering "ping hostname" or "ping IP address" on the command line. If Ping fails, talk your  network administrator and get the correct IP address.


Socket Error 10060 (WSAETIMEDOUT)

Session x (hostname:port) Socket Error 10060 (WSAETIMEDOUT). A connection attempt failed because the connected party did not respond properly after a period of time, or established connection failed because connected host has failed to respond.

This message means that TN3270 Plus has sent communication to the host computer and the host computer did not respond before the end of the timeout period. The timeout period is monitored by the Windows socket, when the end of the timeout period is reached the Windows socket indicates the error to TN3270 Plus and TN3270 Plus reports the error.

This message is normally caused by one of the following:

  1. An incorrect IP address or Host Name in the "Connect to Host" dialog box.
  2. An incorrect port number specified in the "Connect to Host" dialog box.
  3. A proxy server or firewall is blocking communication between TN3270 Plus and the host computer.
  4. Your network uses a VPN (Virtual Private Network) and the VPN is not connected.

Try pinging the host computer to see if it is responding. You can this from the Windows command prompt (Start, All Programs, Accessories, Command Prompt) by entering "ping hostname" or "ping IP address" on the command line. If Ping times out, there is a problem at the host. Talk to a network administrator at the host site and see if they can help you.

(Return to index.)


Socket Error 10061 (WSAECONNREFUSED)

Session x (hostname:port) Socket Error 10061 (WSAECONNREFUSED). No connection could be made because the target machine actively refused it.

This message is normally caused by one of the following:

  1. The remote system rejected your attempt to connect with it, either because no server is listening on the specified port or it's unable to accept any additional connections. Verify you are using the correct port number and then contact the Network Administrator at the host computer site.

  2. You have specified "localhost" as the Host Name in the Connect to Host dialog box. "localhost" is the host name of your PC. Replace localhost with the Host Name of the computer you wish to connect to.

    The Host Name should be the dotted IP address or the DNS name of the host computer. Every computer on the Internet has an IP address that looks something like this "128.228.1.20". To make this address easier to remember, the IP address may be registered and assigned a DNS name. For example, acmecomputer.com. When someone tries to connect to acmecomputer.com a DNS server on the Internet translates that to 128.228.1.20. In this example, either acmecomputer.com or 128.228.1.20 could be used as the host name. Think of the host name as the address of the host computer. It tells TN3270 Plus where the host computer is. You need to find out what the host name or IP address is for the computer you want to connect to. Try talking to the network administrator at the host computer site if you are unsure.

Socket error 11001 (WSAHOST_NOT_FOUND)

Failed to create new socket: Socket error 11001 (WSAHOST_NOT_FOUND). No such host is known.

The name is not an official host name or alias, or it cannot be found in the database(s) being queried. This error may also be returned for protocol and service queries, and means that the specified name could not be found in the relevant database.

This message is normally caused by one of the following:

  1. Specifying an incorrect host name in the "Host Name" edit box in the Connect to Host dialog box.
  2. Specifying the incorrect IP version level in the Connect to Host dialog box. For example, specifying IPv6 for an IPv4 connection.

(Return to index.)


Socket error 11004 (WSANO_DATA)

Failed to create new socket: Socket error 11004 (WSANO_DATA). No such host is known.

The requested host name is valid and was found in the database, but the associated data is not correct.

This message is normally caused by one of the following:

  1. Specifying an incorrect host name in the "Host Name" edit box in the Connect to Host dialog box. 
  2. Specifying the incorrect IP version level in the Connect to Host dialog box. For example, specifying IPv6 for an IPv4 connection.

Session x disconnected by host www.xxx.yyy.zzz.

This message is the result of a disconnect command received by TN3270 Plus.

This message is normally caused by one of the following:

  1. The host computer disconnected you due to inactivity or technical problems.
  2. If you are using an Internet connection

    a.) Your ISP disconnected you due to inactivity or technical problems.

    b.) You were disconnected from your ISP due to technical problems. For example, if you manually disconnect your ISP while TN3270 Plus is connected a host computer you will get the "Session x disconnected by host" message.

  3. There is problem on a firewall, proxy server or router along the connection route.

General Questions and Answers


Can I display multiple sessions in multiple windows so that I can see more than one session at a time?

Yes, most users start multiple sessions in one TN3270 Plus window and use the session tabs to switch from one session to another. This does not allow you to view more that one session at a time. If you want to be able to see more than one session at a time, start TN3270 Plus multiple times. Each time you start TN3270 Plus you create a new window. You may then connect one or more a sessions in each window.

You can set the "Start each session in a new window" option (Setup, Preferences..., Start each session in a new window) to indicate you want each new session in a new window. TN3270 Plus will open a new Window for each new session you connect. You may also specify the "Start in a new window" option for specific sessions. (Setup, Sessions..., Setup Items = Host, Start in a new window").

What screen fonts are available in TN3270 Plus?

TN3270 Plus can use any of the fixed-pitch fonts installed on your Windows system. In a fixed-pitch font, all the characters in the font are the same width. In a variable-pitch font, different characters have different widths. For example, a "W" is wider than an "i". A fixed-pitch font is required to align the characters in the columns on the emulated screen.

Try using Courier New with the style set to bold. This creates a clear readable screen on most monitors at most sizes. Select the font size in the font selection dialog (Setup, Display, Change... button) rather than resizing the terminal Window. TN3270 Plus may "stretch" or "compress" the font as you resize the Window. If the aspect ratio of the window is different than that of the font the font may look distorted. Choosing a specific font size avoids this problem.

Many users like the following fonts. They are free and work well with TN3270 Plus.
