<p>Keyspan updates serial port driver to improve performance</p>
<p>Richmond, California---March 3, 1997---Keyspan, the #1 provider of serial<br />
communications cards for PCI-based Macintosh computers, has released a<br />
driver update for the company's SX line of low-cost, multi-port serial<br />
cards. The SX family delivers affordable and trouble-free serial-port<br />
expansion by providing two or four additional high-speed serial ports on<br />
one easy-to-install PCI card.</p>
<p>Driver version 1.0.1 provides increased performance and fixes some<br />
conflicts users have reported since Keyspan began shipping the cards at<br />
MacWorld Expo, in January of this year. Most notably, Keyspan has improved<br />
single-port performance when configured for port speeds of 230 Kbps. The<br />
update also provides a work-around for a bug found in Apple's Serial- and<br />
Open Transport Serial Port Arbitrators that would not let ports load at<br />
startup. Additionally, the driver update solves conflicts that occur with a<br />
few SCSI devices.</p>
<p>Features, pricing and availability<br />
Keyspan's SX product family supports asynchronous communications at port<br />
speeds of up to 230 Kbps and are compatible with all Communications Toolbox<br />
aware applications. UART-based, the SX cards provide standard RS-232/RS-422<br />
connectivity through mini din-8 connectors. Shipping since January 7, the<br />
suggested retail pricing is $229 for the SX-2 serial card and under $329<br />
for the SX-4 serial card.</p>
<p>Mac users need more serial ports!<br />
MacOS-compatible computers provide only two built-in serial ports. Yet,<br />
many users need to connect a growing variety of serial devices for<br />
communications, mobile computing and desktop publishing applications beyond<br />
the two-port limit. Keyspan's multiport cards offer the serial expansion<br />
users need for: ISDN terminal adapters, modems for e-mail, data transfer<br />
and fax; drawing tablets, certain monitors, serial scanners, label and<br />
other printers; and U.S.Robotics' Pilot and other hand held PDAs.</p>
<p>Unlike port sharing or application juggling products, Keyspan's SX cards<br />
provide real serial ports that deliver a reliable, affordable and<br />
easy-to-use expansion solution. With an SX serial card, multiple ports can<br />
be dedicated to specific tasks simultaneously --- without ever having to<br />
reconnect devices or interrupt existing applications.</p>
<p>Are your cool toys Mac savvy?<br />
Unfortunately, some vendors, perhaps unfamiliar with Macintosh<br />
communications, do not support the Communications Toolbox or even simple<br />
serial-port look-up tables. These applications must be connected to one of<br />
the Mac's two built-in ports. However, there are many instances where users<br />
can still use their built-in ports for those "non-Mac-standard"<br />
peripherals, using the SX card for Mac savvy applications. One fairly<br />
typical prepress configuration is to connect a Wacom tablet, PressView<br />
monitor, faxmodem and Costar label printer to an SX-4 (four-port card);<br />
then hang a digital camera and color inkjet printer or other non-Mac-savvy<br />
device off the built-in serial ports, using the Ethernet port for a<br />
networkable color LaserWriter.</p>
<p>How is the SX family different from Keyspan's Smart Serial 6?<br />
Introduced in January 1996, the SMART SERIAL 6 has become the #1 PCI<br />
serial expansion solution for MacOS-based remote access servers, bulletin<br />
boards, internet servers, file transfer applications, and other<br />
communications servers. Unlike the SX cards, the Smart Serial 6 has a<br />
coprocessor supporting both asynchronous and synchronous communications.<br />
Port speeds on the SMART SERIAL 6 range )from 57.6 Kbps to more than 2<br />
Mbps. In addition to RS-232 and RS-422, the SMART SERIAL 6 supports V.35,<br />
X.21 and other serial interfaces. These added capabilities make the SMART<br />
SERIAL 6 more ideal for high-end applications which require six or more<br />
high-speed ports, or for solutions which involve synchronous communication<br />
such as X.25 and Frame Relay. However, most users do not require the power<br />
which the SMART SERIAL 6 delivers --- they simply use 3-6 serial devices<br />
and need more ports! To meet this need Keyspan has turned its proven<br />
technology design and product support team toward providing a low-cost and<br />
reliable solution in the SX two-and four-port cards.</p>
