First, I want to thank the readers of Serial Port Complete’s first edition and the
readers of my other books and articles. This book is much improved due to the
the many suggestions and comments I’ve received from readers over the years.
For help in preparing the second edition, I thank my technical reviewers: John
Hyde for his generosity, encouragement, and good suggestions; Rawin Rojvanit
for once again providing a thoughtful and expert critique; and Tsuneo Chinzei
for sharing his knowledge on USB virtual COM ports. Thanks to Ron Smith
for wonderful circuits and great conversations about RS-485. Thanks to Steve
Drake for helping me see my writing through the eyes of a typical reader. And
thanks to Jim Hughes for taking good photos.
This book is dedicated to Michele, Pat, and Isie.
