Startech Semiconductor of Sunnyvale (Which seems to have been acquired by Exar www.exar.com) is shipping production quantities of their new ST16C650 Universal Asynchronous Receiver Transmitter (UART) chip. While several companies have introduced proprietary upgrades to the 16550 UART chip, Startech's provides an inexpensive solution for modem and serial board manufacturers wishing to boost the performance of their products.
The 16650 supports DTE rates up to 460,800 bps, and includes all "glue logic" to interface with PCs. It has 32-byte FIFO buffers for both transmitted and received data, compared to the 16550's 16-byte buffers.
More importantly, the 16650 handles all modem hardware/software handshaking. The built-in handshaking offloads work from the online host or terminal software, reducing load on the system processor. With a 16550, software must grab data from the FIFO buffers before it is overrun by new data. As a result, software solutions typically grab the contents of the FIFO buffers when only a few bytes are full, rather than the entire 16 bytes. With the 16650's automatic handshaking, all 32 bytes of the FIFO buffers can be used - a dramatic increase in efficiency.
Alas, there is no upgrade path for existing serial boards and modems as the chip is not pin-compatible with 16550 chips found on existing serial boards. Also, software packages must be modified to take advantage of the 16650. Clark Development's PCBoard BBS software already supports this chip.
The Startech 16650 chip is compact and power efficient - perfect for PCMCIA applications. The chip includes a sleep mode, to reduce power usage to almost zero when not transferring data. The ST16C650 is available in several packages, and costs less than $6 in 1000-unit quantities.
Like GTEK's original BlackBoard-4, the BlackBoard-8 includes their Guardian Watchdog Circuit. Guardian connects between the reset switch in the computer and the motherboard. An included software TSR (Terminate and Stay Resident) program "nudges" the watchdog circuit 20 times per second. If the computer crashes, the TSR locks up, and the watchdog does not get bumped, and the Guardian resets the computer. It will not reset the computer if only a single node crashes. Several BBS packages already support the Guardian technology. Guardian also works with any DOS, Desqview, or Windows-based package. This feature is particularly valuable for mission-critical online systems.
Like the Blackboard-4, the Blackboard-8 is very flexible, supports DTE rates up to 460,800 bps, and is the best 8-port serial card available for the IBM-PC. Sysops and Sysadmins will find the Blackboard-8 a perfect solution for today's 28.8 Kbps modems and beyond.
Micro Logic is known for Info Select for Windows - their powerful free-form Personal Information Manager (PIM). Info Select for Windows has a suggested price of $149, which is a bit hefty for a PIM. Also, it was more powerful than many people needed.
Info Select Express is a trimmed-down version of their Windows-based PIM, with a suggested price of $29.95. It is small enough to fit on a notebook, but capable enough for the power user. Your success with any PIM depends on how much time you spend in front of one computer screen. As with any PIM, becoming proficient with Info Select Express takes some time. There is no manual; all help is online. The online help is very good, although most people prefer printed documentation; but for $29.95...
Eric will lead a tour through gopherspace, describing its layout and easy-to-use features such as bookmarks, file downloading and remailing, and the veronica and jughead search tools. He'll also talk about options for setting up your own gopher server. $3-$5 sliding scale, at the Modern Times Bookstore.
PPP, SLIP, and direct Internet connections offer a glamorous and fun way to use the Net. However, the Internet is primarily based on Unix, and Unix shell accounts are very popular, inexpensive, and useful. Many ISPs include a shell account with a PPP account, and there are some things best done in a shell account.
To use a shell account effectively, some Unix knowledge is required. A great way to get that knowledge is with a copy of Unix Unbound (Osborne/McGraw-Hill, www.osborne.com $27.95, ISBN 0-07-882050-2) by Harley Hahn.
Unix Unbound covers everything an Internet traveler needs to know about Unix. Hahn's style is clear and everything is explained well. There are only two minor problems with this otherwise excellent book: The book has a bias against the Pico editor and Pine mail programs, and the people who use them. Both (related) programs are very easy to use and powerful enough for most people using the Unix shell. Many Shell-account customers will find that Pico and Pine are all they need. We recommend that beginners consider starting with Pico and Pine. If you feel limited, then try other choices.
Another minor flaw is the order of the chapters in the book. After chapter 9, you should read chapters 22-24, and then resume reading at chapter 10. These minor annoyances do not get in the way of our recommendation: well-organized and well-done, Unix Unbound is an excellent choice that we recommend very highly.
Action Arcade Adventure Set (Coriolis Group Books www.coriolis.com, $39.95, ISBN 1-883577-06-3) by Diana Gruber is everything a 'C' programmer needs to create high-quality arcade games for the PC.

For those who want to access the Internet from their home or office, Online Zone sells the latest in software, books, online magazines, wiring supplies, and plenty of help; everything needed to connect to almost any service. It also offers consulting services to individuals and businesses who want to connect to the Internet.
Sysops use Planet Connect systems to download massive amounts of incoming messages and then use normal telephone lines for the return messages. Planet Connect is upgrading the speed of their satellite to BBS solution - now beta-testing a new 100 Kbps link. They also improved their Internet feed, and now have their own domain name of planetc.com.
The interior is Spartan, with apple-crate boxes stacked to the ceiling in narrow rows, all filled with one or two layers deep of all imaginable types of used books. Bring a flashlight to read the labels of the books in the second layers. They have a special room set aside for childrens' books, with readings on Saturday mornings to keep your kids busy while you rummage through the software section. You have to see the place to believe it.
The Roskie & Wallace bookstore is located at 14595 East 14th St., in San Leandro. They are open from 10 AM to 4 PM Tuesday through Saturday. The easiest way to find it is to take I-580 to the 150th St. exit, head West two blocks to 14th St., then go North 3-4 blocks. From I-880, take Hesperian East to 14th. St., then 4 blocks North. A white sign with red letters says BOOKS on the West side of 14th St. There's parking on the North side of the building, which is a connected set of galvanized sheds.

High costs are a factor, but most people are quite happy with the combination of convenience and privacy provided by voice communications. If videophones were free, it is likely that most calls would be made with the camera disabled.
Now that costs for high-bandwidth communications are coming down, companies are rushing to bring us video over networks. Again, the primary application seems to be placing cameras on top of computer monitors, so that we can see each other while we work. Initially, the prospect of seeing clients or co-workers before traveling to meet them is appealing. But that could be accomplished with a .GIF file.
Video over the net, when merged with document or image sharing, is a powerful tool. It's also great for entertainment and some business applications. Putting cameras on top of monitors or phones to "let people see each other while they work" will be met with the same initial "success" as AT&T's videophones did.

Q: What is the difference between Shell account and a PPP or SLIP account?
A: Shell, SLIP, and PPP all describe dial-up Internet connections. Just like a BBS, you dial up an Internet Service Provider (ISP) with your modem. With a Shell account, you are in "dumb terminal" mode - meaning your screen is controlled by the ISP's computer. With a shell account, the ISP is connected to the Internet and you are logged into their machine.
With a PPP or SLIP account, you are actually connected to the Internet. The ISP provides the connection, but all action on your screen is handled by your own computer. This direct connection is usually a prerequisite to using most of the new generation of easy-to-use, graphical application programs.
Q: Which is better, a SLIP or PPP Internet account?
A: Both serve the same fundamental purpose. SLIP is optimized for communications over serial port links and PPP is optimized for modems. PPP is the newer protocol, and is rapidly replacing SLIP as the industry standard for connecting a computer to a network (such as the Internet) over serial communication links. Although both types work, PPP connections are generally easier to install, faster, and more reliable than SLIP connections.
Q: Why is the Internet so slow? I find it no faster with my new 28.8 Kbps modem than with my 14.4 Kbps modem!
A: It is experiencing growing pains. The Internet is an enormous grid of computers and networks. Your modem is only one link in the chain, and the slowest link determines the performance of the connection. Try again later; the speed fluctuates depending on location and time of day.
Q: I visited a WWW site mentioned in a previous issue and got a "connection refused by host" error. Do I need a password?
A: Generally, that error message means the WWW site is busy. Each Internet site has a limited number of incoming ports, bandwidth, and processor power. During peak times of the day, or when a site is mentioned in a publication, you may have trouble connecting - or experience very slow response times. Wait a few hours, and try the same site again. While you are waiting, visit the other million places you can go on the Net.
Q: Where's a good place to look for WWW sites?
A: One source is the latest version of Netscape (ftp it from
e.g., ftp.mcom.com). Or, check the following sites
with lynx or a web browser:
Or, use ftp to get Judith Meskill's directory web pages:
(ftp.netcom.com, cd /pub/jtmax/) w3page.html - The big list
goferpage.html - Gopher sites
wmnpage.html - Women's interest sites
Q: I have been using Procomm Plus for years to call BBSs. I recently got a shell account and I find I can't escape telnet sessions. Procomm Plus doesn't let me use the control-bracket key. Do I have to give up Procomm to connect to the Internet?
A: A common trick among Procomm Plus users is to use the Key Mapping facility to remap the gray insert key (unused in Procomm Plus) to the control-] (^]) key sequence. We chose a different route - upon our first problem escaping out of a telnet session, we changed from Procomm to delta Comm's Telix terminal program (shareware, $39). Telix is easy to set up, easy to use, and does not default to remapping keys used during Internet sessions.
Q: What is a MonoFRAD?
A: It is a device made by the FastComm company (www.fastcomm.com), a one-box solution for those needing a 56K Frame Relay or X.25 connection to the Internet. The MonoFRAD combines a CSU/DSU and a router to link a digital phone line to a local ethernet network. The advantage of a MonoFRAD is its relative low cost. The disadvantage is that, unlike Fractional T-1 equipment, it is not expandable past 56K.
Q: How do I send Internet mail to someone on CompuServe?
A: Take their CompuServe number (e.g., 55555,4444) and change it to 55555.4444@Compuserve.com.

The line between BBSs and the Internet is disappearing. Already, hundreds of BBSs are fully connected. Soon, the number will be in the thousands. We recently discovered Richard S. Mark, a list keeper of telnetable BBSs. Richard is a Sysop of such a BBS, the Dragon Keep International, in Gainesville, Florida. Richard maintains the list under the name of Select BBSs on the Internet (SBI). Similar to our own WCO9412. ZIP list, his list is updated monthly and is currently named SBI9412.ZIP.
How to access a telnetable BBS? First, you must have a real Internet account. From the shell command line, type telnet host_name (e.g., telnet dkeep.com) or telnet ip_address (e.g., telnet 220.127.116.11) You can also access many telnetable BBSs with the Unix rlogin command, although telnet is recommended.
File Transfer Considerations: As of now, most telnetable BBSs do not yet have a File Transfer Protocol (FTP) site. (FTP is the most popular way to transfer files over the Internet.) Dial-up Internet customers can use Zmodem after telneting into a BBS. However, in order for Zmodem to work, the telnet session must be in 8-bit binary mode. The way telnet clients handle mode settings is not standard. Check with your ISP, documentation, or help files to see how this is done.
