Bisync is such an old technology. Isn 3780 emulation going away?
Well, yes and no. Yes, in the sense that eventually the need for bisync connectivity will disappear. But, no in the sense that it has been around for a long time and there is so huge an investment in a bisync infrastructure, especially in the financial and business-to-business sectors, that the phasing out of such a reliable system is often prohibitively expensive. The same thing has been said about the COBOL programming language — it was supposed to disappear years ago but so much of the software in the mainframe world is written in COBOL that it is simply too expensive to do away with it. There are no new large scale bisync systems being installed today, but until existing systems are phased out, which may take another ten years or more, there will continue to be a need for 3780 emulation.
