A dictionary of terms related to modems. It was first released in 1989 as one of the world's first ebooks.
It has been used in training courses by modem manufacturers, as a reference for school term papers, as a reference for Bar Association articles and speeches, and many other uses.
Although it hasn't been updated since 1994, it may be useful as a reference. It is being released in book form primarily to help Parchment Hill test the publishing process, and is 'unpolished' (has not gone through editing, proofreading, etc).
