这是一篇关于利用电路进行早期通信的不错文章，但并没有完全兑现标题承诺的内容。针对那个话题，我推荐 Gerard Holzmann 写的《The Early History of Data Networks》（http://spinroot.com/gerard/hist.html）或者那篇短论文《Data Communications: The First 2500 Years》（http://spinroot.com/gerard/pdf/hamburg94b.pdf）。
This is a nice article about early communications using electrical circuits, but doesn't deliver on the promise of the title. For that I recommend "The Early History of Data Networks" by Gerard Holzmann (http://spinroot.com/gerard/hist.html) or the short paper "Data Communications: The First 2500 Years" (http://spinroot.com/gerard/pdf/hamburg94b.pdf).
