Stay-Linked Thin Client Wireless Terminal Emulation Solutions

Thin-Client Host-Based Terminal Emulation with Advanced Terminal Session Management

General Features

Stay-Linked Server software runs natively on the most reliable platforms, including IBM iSeries, pSeries and xSeries, HP-UX, Sun, SCO, Linux and Windows Servers
Supports IBM 5250/3270, VT220/100/420/52 and SSHv2 terminal emulation
Stay-Linked Thin Clients are available for a wide range of popular wireless devices from LXE, Symbol/Motorola, Intermec, HHP, PSC, Psion-Teklogix, and others – not limited to one device manufacturer
Supports many legacy DOS-based wireless devices (Telxon 960SL, Intermec Anatares, PSC Falcon, etc.) due to thin client design not requiring extensive CPU and memory resources on the device
Stay-Linked Host API for dynamic seamless integration with host screen applications
Option for “dual session” – running two different sessions (same or other host, same or other application, same or other emulation type) at the same time on the same device with a hot-key to switch between (e.g., Alt-S)

Performance

Utilizes proprietary “Micro-Packet” technology to reduce network load (separate packet for each keystroke or barcode scan)
Only net changes to screen displays are all that is sent from the host to the device (does not transmit whole screens unless a new screen is accessed)
Quiet UDP-based Client2Host™ connection technology reduces network utilization (no communication needed with the host when there is no data to send or receive)
High performance is maintained on low-bandwidth or highly utilized networks
Optimized Java code on the server for maximum performance
Optimized C/C++ code for Stay-Linked thin client on the device
Takes maximum advantage of high-performance host server hardware and software
Built-in data compression further reduces network bandwidth utilization
Integrates extremely well with VoIP voice applications running on the same device, communicating on the same network at the same time (no challenging TCP/IP packet prioritization issues to deal with)

Terminal Emulation Session Management

Centralized management console (Stay-Linked Administrator GUI) included
All emulation and terminal behavior configuration and settings are stored and applied on the host system and easily backed-up using existing host system procedures
Eliminates the need to “push” configuration files out to devices
Annual Support and Maintenance includes a free High Availability copy of the licensed Stay-Linked environment (replicate onto a fail-over host system)
Visibility of session status for all connected devices in a filterable, sort-capable “connection list” with intuitive right-click drill down
Wireless transfer of files to and from devices
Send administrative messages to connected devices
Remotely restart or reboot connected devices
Monitor device sessions, viewing the exact screen that is displayed on the device
Dynamically share sessions, enabling help desk staff to perform data entry in the same screen as the wireless device user
Dynamically take over control of sessions when issues occur, enabling help desk staff to exit properly out of any screen applications that were being accessed by the user
Dynamically establish shared access between two or more users/devices to the same screen application session running on the host (Stay-Linked “Session Partnerships”)
Terminate device sessions (individual or multiple) interactively
Transfer control of a user’s host-based session to a new device if their original device becomes unusable
Centralized management of configured Telnet and SSHv2 hosts
Devices can connect to any configured Telnet or SSHv2 host from a single Stay-Linked Server
Centralized Keyboard Mapping by device and emulation type
Centralized management of terminal settings for groups of devices as defined by IP address range and device type
For a group of devices, you can centrally manage these settings and more:
- Host Groups which define what telnet hosts are available to the device
- 5250 Device Naming and OIA display
- Keyboard and Backlight Timeout
- VT Alarm Indication and Handling
- 5250 Alarm handling
- Message Handling
- Barcode Configuration
- Client-side Program Calls
- Client-side Printing Configuration
- Startup Scripting
- Alternate Keyboard Mapping
Management and definition of ‘Tap-Spots’, enabling advanced data entry via the PPC/WinCE stylus in addition to keyboard and scanner input

Device Management

System Information: Displays information about the device, including OS, Processor, Memory, Battery, Display, Locale, Installed Applications and Running Processes.
File Management: Allows interactive management of the file system on the device. Browse the entire file system and use file management features like Create Folder, Copy to Folder, Move to Folder, Delete File/Folder, Rename File Folder plus Download and Upload files.
Registry Management: Allows interactive management of the Registry on the device. Browse the entire registry and use registry management features like Create Key/Value, Copy Key/Value, Delete Key/Value, Rename Key/Value, Edit Value plus Import and Export registry keys.
Network Management: Allows interactive viewing of network properties. View the device’s Network Adapters and Adapter Details, Active Network Connections, Routes, ARP Table, Network Parameters, Access Points, TCP Statistics, UDP Statistics, IP Statistics and ICMP Statistics.
Device Remote Control: Allows interactive remote control of the device itself. This feature allows you to select different color depths and display scales for the remote control session. You can also grab screen shots of the device display in BMP or JPEG formats.
Send administrative messages to connected devices
Software Provisioning: This feature provides a mechanism by which you can build software manifests that will provision 3rd-party or other software onto the device. The Stay-Linked Administrator includes a ‘Manifest Builder’ which will allow you to assemble a custom, script-driven installation package for the various software programs that you require to be installed on the device. Based upon your pre-defined metrics, these software packages will be deployed to and installed on the devices as required.

Centralized Licensing

All licensing controlled via centralized management console (Stay-Linked Administrator GUI)
Cost-effective concurrent-user terminal emulation licensing is driven by a single key value
No need to license individual devices or re-buy terminal emulation when old devices are swapped out for newer ones – true investment protection
Load thin-client software onto as many devices as desired - licensing is based on maximum number of concurrently connected users and not total number of devices – good for spares, and shift workers in multiple time zones, etc.
Add additional licensed seats on the fly – no need to stop/restart the Stay-Linked server on the host system

Security

Using port filtering, no telnet is broadcast over the wireless network--telnet remains on the host
Firewall-Friendly communications architecture
(Port restrictions and Static NAT Configuration for Servers. NAT friendly connections for Clients)
Native, proprietary, end-to-end, application layer encryption technology
(Dynamic-Symmetric 64-bit key, Stream-Cipher Symmetric Encryption Algorithm)
Provides Data layer security to supplement Network layer security – no clear text
Thin Client design and Client2Host™ protocol keeps all Telnet and SSHv2 communication local to the host - secure and not transmitted over the network
Features support for SSHv2 host session connectivity in addition to Telnet at no additional charge
App Lock-Down mode for restricting access to other applications on Windows-based devices
Compatible with all popular network architectures and platforms allowing “port-filtering” or “access list” definitions to be applied at the network switch or smart AP level to restrict host access from wireless devices to Stay-Linked UDP/IP transmissions on specific UDP ports (no rogue wireless devices can access host systems and wireless workers cannot reach destinations other than configured host systems with browser-enabled Windows devices)

Reliability

Utilizes the Stay-Linked Client2Host™ Reliable Protocol to avoid typical “device-side” Telnet/SSHv2 connection problems
Manages wireless user Telnet or SSHv2 Client sessions on the same reliable host as the Telnet or SSHv2 Server process (Clients never disconnect from the Server)
True host-based “Session Persistence” allows devices to automatically reconnect to existing sessions after an interruption, resuming exactly at the same screen and cursor location prior to the disruption (out of range, dead battery, network issue, etc.)
Intelligent thin client detects and identifies network and radio coverage issues
Network and Wireless diagnostic tools on the server and on the client
Configurable secondary Stay-Linked Server host systems in the event that the primary Stay-Linked Server host system is unavailable
Provides support for up to two backup Telnet/SSHv2 Servers per Telnet/SSHv2 host entry
