Emulator High-level Language Application Program Interface (EHLLAPI) standard and API was introduced by IBM for IBM 3270 & 5250 servers, allowing client applications to access information on the host screen. IBM EHLLAPI standard is supported by most of the Terminal Emulator solutions, and forms the basis for many enterprise automation suites and application customization.
As a developer using IBM Host Access Transformation Services (HATS), you can add macros into the HATS application which helps performing repetitive tasks faster and more efficiently. Macros are also the basis for creating RESTful services in HATS.
IBM Personal Communication (PCOMM) provides many features to improve communication with the host application which can be achieved through menu and toolbar operations. Following are some of the most widely ones:
For an introduction to API’s and emulator programming in IBM Personal Communications, refer to the link below:-
IBM Host Access Transformation Services (HATS) allows you to reuse and transform your user experience, by extending terminal applications to the web, mobile, portal, rich client, or as standard SOAP or RESTful web services without touching the existing application.
• IBM Host On-Demand server
• Web browsers:
IBM Personal Communications provides an emulator interface to communicate with IBM Mainframe/AS400/VT sessions. This is used for reading & updating host data and interfacing host with other applications. Performing manual tasks on emulator screen increases in transaction and becomes repetitive, this over a long term would have issues:
IBM HACP Extended Edition is a plugin free, web-based terminal emulator. Unlike IBM Host On-Demand, HACP EE does not download any binaries that run on the client machine. HACP EE reads the existing session definitions from Host On-Demand server and allows users to connect to their System z and System i hosts through an HTML5 compatible browser.
As part of IBM Host Access Client Package v13, there were a few changes implemented in the area of security. These changes are elaborated below:
IBM Host On-Demand comes with a setup of Administration Utilities that are used for various purposes.
Host On-Demand provides graphical user interface for Certificate Management on Windows, Linux and AIX (command line).
