One of the details you didn't mention (because that wasn't the point of the article, I suppose) was the terminal addressing. 3270s had two types of controllers: those that could attach to a byte multiplexor channel on a mainframe and those typically at remote locations attached to a modem. The 3270 addressing scheme allowed for 32 controllers on a channel with each controller able to support 32 terminals. I never saw this even remotely attempted, especially at a remote location due to bandwidth constraints. I think the biggest cluster I saw was 3 controllers, each with 15-20 terminals. Since the 3270 communications protocol was polled, if everyone hit enter at once it could take a long time for the last terminal to send its data. Getting back to the point of the article, one of my jobs in the '70s was to allow 3270s to attach to UNIX. This was a nightmare in many respects. The polled protocol, the full screen read and writes, the difference between EBCDIC and ASCII, the lack of all sorts of normal ASCII keys. The first time we got a "termcap" for it written, watching it try to do vi or emacs (or rogue!) was enough to send the programmers into fits of laughter.，推荐阅读pg电子官网获取更多信息
