Appendix

Detailed Flowcharts
This appendix presents flowcharts that give detailed views of an example
of software logic for implementing full-duplex protocol. The flowcharts
in Chapter 4 gave you a simplified view of this software logic.
We have not shown any error checking or recovery relating to interaction
with the modem handshake driver, a third process. To do this would
overly complicate the flowcharts and, in many cases, such error checking
and recovery are not needed.
Here is a list of the figures in this appendix:
