Companies that have embraced computer technology for many years will have programs that they have inherited from earlier platforms, utilizing technology that is “more primitive” than that currently available. These programs are known as legacy programs and can prove problematic for some companies. Legacy programs are found in all fields of work including transportation, logistics, manufacturing and retail. Since these programs are written for earlier operating systems, the challenge for these companies is to integrate them with current technologies, in particular handheld computer devices. Short of completely rewriting the program, terminal emulators are often used to enable access to these programs on all devices with minimal fuss.
A terminal emulator is designed to make a computer terminal appear to look like an old terminal with no intelligence. This is useful in these scenarios as a terminal emulator can be used in order to make a modern computer appear like an older one. This then allows access to legacy programs that could otherwise not be run on modern computers and handheld devices. Earlier terminal emulators had to account for the lack of processing power that handheld computers have through the use of a server. The software is installed on the server that then does all the processing work for the devices that connect to it. You may already see the flaw in this plan, as an error with the server would knock out every device requiring it to run programs. This is costly not only in repairs, but also in the downtime that is experienced by the entire fleet of devices that are no longer functional. The need for an intermediary server has been eliminated as modern handheld devices have enough processing power to run terminal emulators directly and as such any failure will be completely isolated from the rest of the devices.
Wavelink Terminal EmulationWavelink have developed a terminal emulation software that makes it quick and easy for companies to use mobile computers to access legacy software. Wavelink uses a program known as TermProxy, a server software that allows the persistence of the session despite loss of connection or the device goes to sleep. This eliminates the need to repeat a log in or relaunch an application. More importantly these devices have extensibility so that modules can be added, allowing new and constantly improving features. An example of this is voice technology, something that is utilized often in picking. The ability to integrate voice technology with the terminal emulator existing within the device has the potential to save companies the time and money required to create new programs and applications.
Wavelink’s terminal emulation provides RFID support so that whilst still using a legacy program, it is possible to input data through RFID means, a process that saves valuable time and prevents inaccurate data entry. Add to this impressive security features, a strong troubleshooting support and application automation, and it is easy to see what makes the Wavelink terminal emulator a powerful tool for any company.
Terminal emulation is a powerful tool that allows the running of legacy programs. Whilst previously a difficult task involving the use of an intermediary server, recent improvements have seen devices such as the Wavelink terminal emulator created with the company and efficiency in mind. The features and flexibility provided mean that there is little inconvenience to the company resulting in increased productivity.
