Aug 31, 2015 The IBM i System (aka i5 aka iSeries aka AS/400) uses something called 5250 to stream its data to a terminal, often called a green screen. You’ve seen this clunk old terminals in black and white scifi movies – well we still use them.
This topic contains multiple sections.
- RFC 1205 5250 Telnet Interface February 1991 to indicate that the work station is no longer invited. 4.3 System Request Example The 5250 System Request operation is invoked when a client wants to interrupt the server job to perform some function. The typical scenario would be for a user to press the system request key, or whatever key is mapped to a system request key, which would cause the.
- The 5250 Telnet server enables clients to negotiate both terminal and printer device names through Telnet Environment Options Negotiations, defined in the Standards Track RFC 1572 13. The purpose of RFC 1572 is to exchange environment information using a set of standard or custom variables.

A few of the 'Actions' that submit but do not send Aid Key to the IBM i need to effect the Telnet message header instead. According to http://www.ietf.org/rfc/rfc1205.txt, there is a 16 bit flag field in the Telnet header. Eight of those bits are reserved and should be set to zero.
|This bit is set to indicate a data stream output error. The negative response code is sent as data following the op code field.|
|This bit is set to indicate that the 5250 attention key was pressed.|
|These bits are reserved (set to zero).|
|This bit is set to indicate that the 5250 System Request key was pressed.|
|This bit is set to indicate that the 5250 Test Request key was pressed.|
|This bit is set to indicate the Help in Error State function. The error code is sent as data following the header and is a four digit packed decimal number. For example, an error code of '0005'X indicates the operator attempted to type in an area of the display that is not enabled for input.|
|8 thru 15||*||These bits are reserved (set to zero).|
Customizing the Keyboard
When keyboard input is identified, the input is normalized into a Key object with the following properties:
inputKey, wasKeyPress, outEvent
|Key object described above with the properties populated with information from the Browser event that caused it.|
|Boolean indicating the origin of the input. |
|Input event object instance. This is the object we need to change to indicate the mapping. the two properties are: |
Where action should be assigned a string value and character should be assigned a string value with one character to be added at the cursor's position (if positioned at an input field).
Only one of the properties should be changed unless that key event should be processed by the default action or character.
For example, the following implementation of global function
WingsTerminalMapKey will map the 'RESET' action to the Ctrl + R key combination. Note: the default 'Esc' mapping would still work. To disable the default code, map it to a blank action.
Adding Hot-keys for International Characters
(when not available on keyboard)
Even the numeric keypad (when Num Lock is ON), may be used to enter characters – giving its ascii code. For example, Alt 164 on US keyboard produces the 'ñ' symbol - it may be simpler to remember to produce these, by a combination with the Ctrl key. You can easily map 'ñ' or accent on vowels with a sequence such as Ctrl, like in the following example:
Note: When re-mapping the keyboard, please test under the three supported Browsers: IE7+, Chrome, and Firefox.

This section describes the variousmeans provided to group and define your Telnet hosts that will be accessed fromeach StayLinked server. You can define one or more Telnet hosts per server towhich your wireless users will connect.
Telnet Hosts are organized into ‘Host Groups’ that can be assigned to ‘Device Groups’, allowing you to control what Telnet hosts are available to specific devices. Various host groups can be created to provide multiple configurations of hosts, as required by your architecture. When more than one host is defined for a host group, the list of hosts will appear as a menu on the wireless device when a new session is started and the user will be able to select the Telnet host to which they’d like to connect.
This selection process can also be automated using the “preferred host” setting. Clients using the custom configuration file ‘connections.ini’ can receive a new version of this file from the StayLinked server. For those devices not configure for Multiple Connections, the preferred host setting can be distributed to client for using the Administrator’s client settings.
In the following example, you can see the mandatory ‘Default’ host group, plus we have defined a few additional host groups. The ‘Default’ host group may be changed, but not deleted.
Telnet 5250 Keep Alive
Maintaining Host Groups
When you select ‘Telnet Host Groups’ from the server tree or the Manage menu, the Telnet Host Groups list will appear in the main display panel. Each StayLinked server will have a ‘Default’ host group, and you can add other host groups as required. Clicking the right mouse button in a blank area or on a host group will cause a small menu to appear with options to Add, Edit, or Delete a group.
Additional options include:
Screen Recognition Quick Access – This allows the Administrator to open all of the existing screen recognition events in this telnet host group for quick adjustments. It does not allow the creation of new events, which must still be completed by navigating the to desired host entry.
Manage Screen Maps – This opens a list of all screen maps for all hosts. Management of screen maps outside of the host entries allows renaming to be applied to all references among all host entries, even those in multiple host groups. Screen maps referenced in any host group cannot be deleted until the reference is removed.
When you select the Delete option, you are prompted for confirmation. If you select the Add or Edit options, the following window will appear where you can enter/edit the host group definition.
The host group has a ‘Group Name’plus two additional options. These options will only affect host groups thatcontain more than one host entry. If there is more than one host entry, a usercreating a new connection will be presented with a menu on the device screenfrom which they can select the desired host. If the menu is displayed, you cancontrol these two options:
Telnet 5250 Protocol
- Use ‘Group Name’ as Menu Title: Check this option to have the ‘Host Group Name’ displayed as the title of the host selection menu on the device screen. If this option is not checked, then the menu title will default to ‘Select a Host’.
Display ‘Quit’ on the Host Menu: Check this option to include a ‘Quit StayLinked’ option on the host selection menu. The ‘Quit StayLinked’ menu option enables you to cancel the connection and return to the main StayLinked Client Menu on the device, without connecting to a Telnet Host.
For the host group, you may alsoadd, edit, copy, paste, delete and change the order of the Host entries usingthe “Hosts” menu or by clicking with the right mouse button in the host list.
Copy and Paste for Host Entries: These options provide a convenientmethod to copy a pre-configured Telnet Host Entry from one Host Group and pasteit into the same or another Host Group.
The two additional options are not available for the ‘Default’ Host Group. If you want to take advantage of the Use ‘Group Name’ as Menu Title option or the Display ‘Quit’ on the Host Menu option, then you will have to add a new Host Group where these options will be available. You can then use the ‘Device Group’ feature to make your new Host Group available to your devices.
Maintaining Host Settings
When you add or edit a Host Entry within a host group, the following window will appear that shows the current host settings and allows you to make changes.
Name: This is a descriptive name for the Telnet Host, i.e.:“Production SAP”.
Address: This is the Host Name or IP address for the Telnet Host.
Telnet Port: This is the Telnet Port for the Telnet Host, typically port 23. If your host requires a different port for each session, there are two options available. The first is to create a device group that points to a telnet host entry for each connecting device. This is simple for a small number of devices, but does not work well when many devices need this configuration. The best option is to use the Emulation Property at the bottom of the Telnet Host Entry for “DeviceID as the Telnet Port”. Note that this setting may not appear in older versions of the Server and Administrator. Right Click and select Add in the list box for Emulation Properties:
Once this setting is in place, Clients Configured with a port number in the DeviceID value will use that number for their session port. Details on DeviceID can be found in the article for Device Naming.
Emulation: Select the type of client emulation to use when connectingto the Telnet Host.
- EmulationTypes: 5250, 3270, TESS or many VT emulations, including UTF8 and SSHv2, tochoose from. (See Secure Communications Guide for details about SSL-Telnet andSSH connections.) Note that SmartTek licensing is only usable by select Zebradevices and is required in order to connect to TESS emulation hosts.
- SHARE-IP,SHARE-ID or SHARE-MAC: These SHARE options will enable a device to share asession with another StayLinked device that has already established a terminalsession. The one requirement for ‘Sharing’ a session is to identify the devicethat is running a session that you want to share. The server will prompt theuser for this identification value, depending upon the SHARE-type selectedhere. The user will be required to scan or type the target device’s MACAddress, IP Address or Device ID. Once this value is provided, then the serverwill look for a running session that matches the value provided. If a sessionis not found, then the user will be notified and will be prompted to re-enterthe identifier. If an active session is found, then the device will beconnected to that session and begin sharing the terminal session with theoriginal device. The original device still ‘owns’ the session and this deviceis only sharing the session. Both devices can type or scan into the session andboth devices will see screen updates to the session. When the device is donesharing the session, the user should select to ‘Exit’ the session. The ownerdevice will still have control of the session and will be able to continueprocessing.
- PGMCALL:The PGMCALL emulation type enables the StayLinked Server to cause the device torun a program that is installed locally on the device. So, if you select thisHost Menu option, rather than connecting to a telnet session, the specifiedprogram will be run locally on the device. When you select PGMCALL, only twoother settings are used by the system. The ‘Name’ entry will contain thedescription of the program call that will be displayed on the host menu on thedevice. The ‘Address’ entry will be used to enter the name of the program to becalled on the device.
Example: Emulation: PGMCALL, Description: Print a Label, Address: PRINTLBL.EXE
For some DOS devices with limited RAM, you can cause the StayLinked Client tobe removed from memory before running the local program. Just enclose theprogram name in square brackets . The square brackets will notify theStayLinked Client that you want to use the entire available RAM to run thelocal program. In this case, the StayLinked Client will exit, the local programwill run, and when complete, the StayLinked Client will automatically restart.
- DMONLY:The DMONLY emulation type enables the StayLinked Server to cause the device torun a Device Management Only session. There will be no Telnet or SSH accessprovided in this Device Management Only session. The client software willbehave much differently on the device when the client is running a DeviceManagement Only session.
The ‘Device Management’ features havebeen end-of-life since September, 2015.
Size: You canselect the size of the Telnet Session Screen. This value refers to the ‘telnetsession screen’ that resides on the StayLinked server, not the size of thedevice view port. The available values depend upon the type of client emulationselected.
ViewPort: These settings describe how to handle the device viewport for the Telnet Host. For example, a small wireless device might have a screenthat can support 20 columns and 15 rows. The Telnet host is putting out 80columns and 24 rows. The view port then is that part of the full screen that isdisplayed on the small device screen.
- Locked:Check this box and set the Coland Row for the upper-left corner of the locked view port.
- Followthe Cursor: Check this box to ensure that the view port on the device willfollow the cursor if the application positions the cursor outside of thecurrent view port.
Caps Lock: Checkthis box to force all keyboard entry to this Telnet Host to be capitalized.
Clear Field on Data Entry: For 5250 and 3270 hosts, check this boxto cause the current field to be cleared when data is typed into the firstposition of, or when a barcode is scanned into the field.
Keyboard-Only Field Attribute: For 5250 and 3270 hosts, select thefield attribute that will designate a ‘keyboard-only’ field. All fields thatmatch the selected attribute will allow only keyboard data to be entered intothe field. Scanner data will not be allowed into these fields.
Scan-Only Field Attribute: For 5250 and 3270 hosts, select thefield attribute that will designate a ‘scan-only’ field. All fields that matchthe selected attribute will allow only barcode scans to be entered into thefield. Keyboard entry will not be allowed into these fields. This attributemust be different from the Keyboard-Only Field Attribute.
Tap Spots Collection: You can select the Tap Spots Collection thatyou wish to use with this Telnet Host.
Host API Configuration: These options control the behavior of theStayLinked Host APIs.
- SeparatorChar: You can specify the hexadecimal value of the displayable characterthat will be used as the separator within the Host API data on the screen.(default is 0x7E for tilde, ~)
- Row and Col: Allows you tospecify the row and column where your end-user applications will displayStayLinked Host API data. The row and column should reflect the screen positionof the first separator character in the API command specification. The defaultHost API location is row 1 and column 2.
- Show APIScreens: You can use this checkbox to select whether or not to show thescreen containing the Host API data to the user on the device.
Host Startup Script:You may define a startup script for this Telnet Host. The startup script willbe processed only when a new session is established. The script will not be runwhen a device reconnects to an existing session. The script will always beprocessed against the first host screen that is presented to the device, typicallya logon screen. The script can be up to 255 characters in length. The scriptcan contain any combination of characters and emulation mnemonic keywords.Emulation mnemonic keywords are contained within square brackets . Specialscripting mnemonics are detailed in the appendix at the end of this document.You can select mnemonic keywords from the ‘Insert mnemonic’ drop-down list,causing the selected mnemonic to be automatically inserted at the currentcursor location within the script textbox. Syntax errors in the script will notcause errors, but may cause portions of your script to be ignored by theemulation host.
- Startup Script example:myuserid[fldexit]mypasswd[enter]
The example 5250 Startup Script above is designed to beprocessed against a 5250 logon screen. The user profile ‘myuserid’ will beautomatically typed into the first field on the screen and then the ‘FieldExit’ mnemonic will be processed, moving the cursor to the next field on thelogon screen. Then, the password ‘mypasswd’ will be typed into the currentfield and the ‘Enter’ key mnemonic will be processed. This script would cause auser to be automatically signed onto the target IBM I Telnet host.
Reconnect Script: You may define a reconnect script for this TelnetHost. The reconnect script will be processed only when a device reconnects toan existing session, or when a device switches between multiple sessions. Thereconnect script is most valuable for voice-enabled sessions and can be used tonotify the application that it should repeat the last Text-to-Speechinstructions and the last Voice Rules instructions.
Emulation Properties: Depending upon the emulation type selected,you will have additional properties available that can be used to adjust thebehavior and settings of the Telnet client. A list will appear at the bottom ofthe Host Properties window showing the emulation properties that have alreadybeen defined for this host and their values.
You can right-click within the listarea or use the Properties menu to add, edit and delete the EmulationProperties for this Telnet host. Emulation properties that have been added tothis list box will no longer appear in the pulldown. Some emulation propertieswill have different names, usage or options depending on your emulation type. TESSemulation properties are described in the support guide for TESS emulation. 5250,3270 and VT properties include:
- Host Backup1 & 2 Name/IP – Determines the 1st and 2nd backup host IPs orhostnames.
- HostBackup 1 & 2 Port – Determines the 1st and 2nd backup host portnumbers.

- Enable Telnet Proxy Processing – Causes the Telnet Session to connect through an integrated proxy that will record the inbound and outbound telnet traffic to a log file and/or scrub telnet traffic of invalid VT ESC Sequences. (VT only)
Proxy Scrubbing was added in v12.1 build 128 to aid in the processing of unsupported sequences from the telnet host data stream. The original implementation removed the combination of escape followed by any control code.
0x1B plus 0x00 thru 0x1F is converted to two spaces
The setting for Proxy scrubbing was enhanced in Server v15.0 build 206 to nullify the following Digital Equipment Corporation (DEC) escape sequences from the telnet data stream:
0x1B 0x7E (ESC ~) DEC sequence for Locked Shift – Map G1 into GR
Starting in Server v15.0 build 208 the following additional sequences are removed by Proxy Scrubbing:
0x1B 0x56 (ESC V) DEC sequence for Start Protected Area
0x1B 0x57 (ESC W) DEC sequence for End Protected Area
0x1B 0x46 (ESC F) DEC sequence for Start Selected Area

- SessionLU Name – Must be a valid LU name of or LU pool name. (3270 only. Requires'Enhanced TN Session' enabled)
Manage – Alt Keyboards(menu option) Alternate Keyboard Maps: For Telnet Hosts, you can overridethe keyboard map that a device would normally use and specify a differentkeyboard map to be used as an alternate.
Keyboard maps are used by the StayLinked system as a cross-reference between the many and varied device keyboards and the various host types (5250, 3270, and VT). With StayLinked, you can use the default keyboard map or alter it to suit the specific needs of your device users and their applications. In addition, you can create alternate keyboard maps to support variations needed for a specific host or group of users.
In this example, when an IntermecCK71 Windows Mobile 6, Alpha-Numeric keypad device connects to this Host, thealternate keyboard map for the Intermec CK71 Windows Mobile 6, Numeric keypaddevice will be used instead.
You may add and delete thesealternate keyboard maps using the Keyboard menu (the Add New Alternate Mapselection window is shown above). The Original Map and Alternate Map dropdownsprovide a list of available keyboard maps from which to choose.
In case you are using Custom DeviceTypes for your devices and you want to map them to an existing standardkeyboard map, you may select the special value ‘** Enter a Custom Device Type**’ as the ‘Original Map’. Then select the desired existing ‘Alternate Map’.When you click OK, you will be prompted for a ‘Custom Device Type’ value thatwill be used for the ‘Original Map’ value.
Telnet 5250 For Sale
Select “Save Changes” from the“File” drop-down menu to save any changes that you have made to the currentlyselected host group.
Manage – Barcodes (menu option) Barcode Settings at the Telnet Host Level: If your device belongs to a ‘Host Group’ that contains more than one host with different emulation types, then it might be valuable to have different barcode settings for the different types of emulation hosts. For instance, if your Host Group contains a 5250 Telnet host entry and also contains a VT220 Telnet host entry, then you might require different barcode suffixes for the different hosts, like a Field Exit [fldext] for the 5250 host and an Enter [enter] for the VT host. The configuration of barcode settings for a Telnet Host entry is identical to the configuration of barcode settings for ‘Device Groups’ as described in the Managing Barcodes sub-section of this guide. The barcode settings that you define at the ‘Device Group’ level have priority over any barcode settings that you define at the ‘Telnet Host Entry’ level.
Manage – Screen Recognition (menu option): For telnet hosts, you can define screens to be recognized and actions to take for those recognized screens. You can grab ‘Variables’ from the screen text that can be used as arguments in ‘Host APIs’ or ‘Auto-Responses’ associated with the recognized screen. You can specify ‘Host APIs’ to be processed when the screen is recognized. You can specify ‘Auto-Responses’ which are scripts to be processed when the screen is recognized.
