HAYES INTRODUCES INTERNAL 288 V.FC MODEM
WITH HAYES ESP INCORPORATED
Atlanta, GA, 20 May 1994 -- Hayes Microcomputer Products, Inc. today
announced the availability of OPTIMA 288B V.FC + Fax for US$499 and CDN$599.
Incorporated onto this internal modem card is Hayes ESP Communications
Accelerator. The integrated Hayes ESP COM Port Technology is a custom 16-bit
communications co-processor which allows OPTIMA 288B V.FC to achieve full
data transmission port speed of 230,400 bit/s in multi-tasking environments
such as Windows.
This internal data + fax modem supports V.Fast Class (V.FC) for
28,800 bit/s (28.8 bit/s) data transmission; ITU-T V.42bis data compression;
ITU-T V.42 error-control; and Group 3 fax using V.17 for 14,400 bit/s fax
transmission.
This product is also fully compatible with the installed base of
V.32bis (14.4 bit/s), V.32 (9600 bit/s) and V.22bis (2400 bit/s) modems. In
addition, OPTIMA 288B V.FC will operate at 28,800 bit/s with future Hayes
products implementing the V.34 (V.Fast) standard once it is approved. Hayes
will make an upgrade to V.34 (V.Fast) available at a cost of less than US$100.
In order to achieve its superior throughput, Hayes OPTIMA 288B V.FC
supports an enhanced and well optimized implementation of the V.42bis
standard, as well as a larger dictionary than other modem vendors in order to
improve performance for a wide range of file types. Examples of files that
consistently achieve superior throughput rates include graphics files, text
files, e-mail message files, database/spread sheet data and other types of
user generated data.
It is a common misconception that an internal modem plug-in card
will not suffer the same throughput and data loss problems as an external
modem attached to a serial port. The combination of Hayes high-speed OPTIMA
technology and Hayes ESP provides reliable high-speed communications for
users who prefer an internal plug-in modem solution. With Hayes ESP's
dedicated co-processor, users benefit from built-in automatic flow control to
ensure data integrity by eliminating buffer overrun errors experienced with
even the 16550 UART at speeds of 115.2 bit/s or higher. The ESP COM Port
Technology is the only serial architecture to support speeds above 115,200
bit/s in Windows or network operating system environments. To maximize the
PC's performance, Hayes ESP provides dual 1024-byte send/receive buffers and
a 16-bit PC Bus interface for superior I/O performance.
OPTIMA 288B V.FC + FAX comes with a two year limited performance
warranty which is extendable to five years when customers register the
product within 90 days of purchase (US & Canada only). OPTIMA 288B V.FC +
FAX is bundled with Smartcom for Windows LE and Smartcom FAX for Windows
communications software.
