Chapter 10 – describes how to write a full–duplex line driver to enable

a computer to communicate to the 1775–KA’s RS–232–C channel.

Chapter 11 – describes how to write a half duplex line driver to enable

a computer to communicate to the 1775–KA’s RS–232–C channel.

Chapter 12 – describes the network and application layers of a software

driver to enable a computer to communicate to the 1775–KA’s
RS–232–C channel.
