-
- The title overstates the case a bit here. To begin with, the serial
- communications are to take place only on an RS-232 port. The promise
- of the inclusion of LAN technology refers only to a brief discussion
- of the Novell NetWare Asynchronous Services Interface (NASI); a means
- of accessing a COM port over a LAN. The COM port had better be on an
- MS-DOS machine: other than mentioning that the Macintosh serial ports
- are not "true" RS-232, they don't rate any ink. Finally, the
- communications had better be with a modem or host computer. This
- might be the primary use of MS-DOS COM ports, but there isn't even the
- slightest mention of the possibility of using serial communication for
- process control or data collection.
-
- Within those limits, Gofton has written an interesting book. The
- coverage is quite distinct from other personal computer communications
- guides. Gofton states that he is interested in a technical resource,
- and does give significantly more detail in some areas than other
- works. On the other hand, he is surprisingly coy about some topics.
- The difference between band and bits per second is mentioned, but
- never defined. The Hayes "AT" command set explanation is possibly the
- best I have seen to date, but there is no help with diagnosing the
- most common parameter setting mistakes. The modem reference explains
- V.32, but not V.42, MNP levels or 14,400 bps modems.
-
- Part of this may be due to the fact that the book appears to have been
- hurriedly updated from the 1986 edition. All references are to the
- RS-232-C version, rather than the more recent D version (more properly
- referred to as EIA-232-D). The importance of IRQ settings is
- explained, and COM3 and 4 are mentioned, but there is no explanation
- of the means of using COM3 and 4 given that most configurations only
- allow you to use two IRQs.
-
- Gofton's writing style is clear and, when he gives sufficient
- information, is quite suitable for the end user. The communications
- novice, given a necessary level of interest and perseverance, should
- be able to obtain a lot of useful material from the first half of the
- book. The utility to the programmer, or more technically advanced
- user, is problematic. However, even the experienced programmer, if
- approaching serial communications for the first time, could get a lot
- of value from this book.
