Huh, intriguing. And look at that up in the corner of the keyboard... HOME = ~
Now that makes sense, too. :)
For three bonus points ... what does the HERE IS button do?
Can't figure it out. Tell us! :)
I guess the teletype interface is truly in the dustbin of history (where it belongs, no doubt).
Pressing HERE IS causes a teletype device (the ADM3A is one) to send its station identification, if equipped with an answerback option. The reception of an ENQ (CTRL-E) character from the far end also causes the device to transmit its identification.
I never saw an ADM3A that actually had an answerback option. The Lear-Seigler folks must have imagined they were going to sell this baby as a glass telex. Then Bill Joy developed vi, and business took off.

Mr. Jones didn't reply so I looked it up:
Not as interesting as I had hoped... maybe someone can offer some context.
Perhaps it is to print the working directory; $ pwd.
It does make the cursor blink, maybe?

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
