- Most computer users, even those dealing with communications and
- modems, will not have to deal with the intricacies of the RS-232 (or
- EIA-232E) interface standard for serial communications. You buy a
- cable, plug in the modem, and that's the end of it. For those who do
- want to know more, this book is fascinating -- as well as being
- completely accessible for the non-technical reader.
-
- Part one deals with the interface, reasons for an interface standard,
- and the general concepts and tools needed to attack an interface
- problem. Part two is primarily a series of "case studies" and
- specialized examples. Interestingly, Campbell nowhere gives a full
- listing of the RS-232 pin assignments, concentrating on the "Big
- Eight" which do form the foundation of almost all serial communications.
- The chapter on the Mac is most interesting -- the Mac does *not* have
- an RS-232 port, relying instead on a subset of the EIA-422 standard.
- Some notes are odd, however. The juxtaposition of a marginal note
- complaining about the IBM PC asynchronous (serial) port is placed,
- without comment, next to a discussion of male and female connector
- assignments. Read carefully, it indicates that IBM was right, but it
- may confuse some readers.
-
- Those who want the full technical details of the interface
- specification will have to get them elsewhere. Few will want as much
- detail on printers as is given here. For those hobbyists truly
- interested in the interface, this is an intriguing, and potentially
- quite useful, source.
