(An) alt approach: state what the developments and changes are and explain how they will improve business.” To call Virtel Web Access a game-changer might be doing it (and you) a disservice. To be clear – it is that, and so much more. Explaining the developments and how they will improve your business is the easy part. ## **Why replace client-server 3270 emulators?** Gone are the days of heavy, client-based, TN3270 emulators, many of which could only run on the obsolete Internet Explorer platform. [Virtel Web Access is a thin client, browser-based 3270 terminal emulator](https://blog.virtelweb.com/covid19-and-3270-applications-access-how-syspertec-bridged-the-gap), serving 3270 screens as HTML and JavaScript pages, with 3270 emulation ergonomics to devices straight off the mainframe without middle-tier servers. Deployment is simple and straightforward with nothing installed on client devices - everything resides securely on the mainframe. Virtel Web Access runs flawlessly on a standard web browser (and yes, we mean any browser) on users’ desktop or device to provide TN3270 access, making maintenance and support issues virtually non-existent. If the internet is up and running, Virtel is up and running.
