FileKit & 3270 Terminal Emulation Software Most users today rarely connect to IBM Mainframe systems using actual hardware 3270 terminals but do so using emulated 3270 terminals running on a PC workstation. Many of these 3270 terminal emulation products contain features and functionality that exceed that of a standard hardware 3270 terminal and keyboard. This allows tailoring of the look and feel of the individual's IBM Mainframe environment. FileKit provides the user with a windowing environment within a 3270 session (i.e. supports multiple window display, window repositioning, resizing, maximising, etc.) As such, CBL has identified certain features offered by 3270 emulator packages that facilitate use of the FileKit environment. The following table identifies commercially available 3270 emulation software products that have been tested at CBL and their ability to support those features pertinent to usage of FileKit. It does not, however, reflect the vast range of other facilities available in each product. Large Screen Sizes TN3270 terminals, served by the host TELNET server, may reference VTAM LOGMODEs that support non-standard screen sizes (i.e. indicate that a read partition query is to be issued by a host application to determine the capabilities of the device.) Standard screen size LOGMODEs are often referred to as Model 2/3/4/5 terminals and correspond to actual hardware 3270 terminals. Comprehensive 3270 emulator support of IBM-DYNAMIC TN3270 terminals will allow the user to specify the desired 3270 screen size (rows x columns) e.g. 40 x 132, 62 x 160 (maximum supported by ISPF), 86 x 190, etc. Starting FileKit in a 3270 terminal of larger than standard dimensions allows the user to view more windows concurrently and to display more information within each window. Note that, when using terminals with large dimensions, it may be necessary to reduce the font size and/or increase the resolution of the

What is an IBM 3270 (TN3270) Terminal?The IBM 3270 is a series of block oriented computer terminals (sometimes called display devices) made by IBM.They were originally introduced in 1971 and they were used to give users access to programs running on on IBM mainframes.Unlike popular character-oriented terminals of that time (like VT220 orANSI), the 3270 minimizes the number of I/O operations over the network between terminal and mainframe,but it requires more computing power inside the terminal itself to handle the complexity of the 3270 protocol(six years later, IBM also introduced a similar but less complex terminal, intended to access IBM's midrange computers,this terminal was then called 5250).The 3270 series was designed to connect with mainframe computers, often at a remote location, using the technologythen available in the early 1970s. The major design goal of 3270s are minimizing the amount of data transmitted.In a data stream, both text and control (or formatting functions) are interspersed allowing an entire screen to betransmitted between the server and the 3270 terminal as a single output operation (originally using coaxial cableand IBM's Token Ring network, later via ethernet and then TCP's telnet protocol TN3270).Since Token Ring connections are no longer in use these days,today TCP/Telnet is mostly used as a transport, hence the emulation isnow also often named in conjunction with the Telnet transport and called TN3270.Although IBM no longer manufactures physical 3270 terminals, the IBM 3270 protocol is still commonly used viaterminal emulation to access mainframe-based applications, especially inlarge organizations like banks or insurance companies. Block Oriented vs. Character Oriented Terminal EmulationAs mentioned, the IBM 3270 is a class of block oriented computer terminal, while the popularVT220 is character oriented.With block oriented terminals like the 3270 (or 5250), exchange between terminal and server isbased on whole screens. This is akin to the server sending a form to the user, where the usercan fill data into the various fields of the form without interaction between terminal and serverand then sending the whole data back in one block. This requires some computing to be done on theterminal, because the 3270 terminal needs to control the input (e.g. restrict data to be filledonly into a screen location where the screen form has an input field).Using a method known as "read modified", a transmission back to the mainframe contains only thosefields in the 3270 terminal screen, where the user made changes. This technique lowers the load on theCPU (because it has to deal with less input)and generally minimizes the amount data transmittedover the network between the 3270 terminal and the mainframe.Character oriented terminals like VT220 orxTermare quite different in that regard, because they transmit every single user keystroketo the server and the server computes the proper response (e.g.
