           HAYES TO SUPPORT V.34 IN 230,400 BIT/S MODEMS

        ATLANTA, GA, 27 June 1994 -- Hayes Microcomputer Products, Inc. 
today announced its plans to provide high-speed data and fax modems that 
support both the ITU-T V.34 standard and the V.FC interim industry standard 
for 28,800 bit/s data transmission.  Hayes plans to make these products 
available to the global marketplace beginning this fall to coincide with the 
ITU-T final approval of the V.34 standard.  This decision was based on the 9 
June 1994 ITU-T approval for letter ballot of this standard and Hayes 
commitment to support international standards.  Hayes also announced its 
plans to offer an upgrade to V.34/V.FC for its existing V.FC customer base in 
the United States and Canada.

          Right now everyone is focused on modem modulation because of the 
recent ITU-T vote,  said Hayes President Dennis C. Hayes.  "What the industry 
needs to focus on is not only the new standard but also on issues such as 
managing the transition to V.34, support of the current 288 installed base as 
well as the speed and performance of modem applications."  

        By September 1994, within the first year of being in the market, 
V.FC modems are estimated to gain an installed base of approximately one 
million units.   In addition, more than 4,000 bulletin board lines support 
V.FC modulation using Hayes modems.  "V.34 is more complex than any previous 
modem specification and it has taken longer than anyone expected to define 
the standard.  Interoperability of different implementations of the standard 
may be a problem for the first few months of availability. " added Hayes.  
"Because of the large installed base of V.FC modems and initial concern about 
V.34 interoperability, users should ensure that their 288 modems support both 
V.34 and V.FC."

        For the first 90 days after Hayes begins shipping V. 34/V.FC modems, 
Hayes is offering a free upgrade for OPTIMA 288 V.FC + FAX and ACCURA 288 
V.FC + FAX customers with the purchase of a like Hayes V.34/V.FC product.  
During that time customers who choose not to purchase a Hayes V.34/V.FC modem 
can upgrade for only US$49.  Hayes will provide free upgrades to Hayes BBS 
Sysops who have obtained their product through the Hayes Sysop program.

        Once the upgrade is available customers should ship their modems to 
Hayes, at which time Hayes will upgrade the product and ship the modems back 
to the customer within the same day.  For those customers using modems to run 
mission-critical applications that must remain in service, Hayes is offering 
a "hot-swap" program.  These customers should contact Hayes Customer Support 
and Hayes will pre-ship V.34/V.FC modems to them.  Upon receipt of the 
V.34/V.FC modems, customers should then ship their V.FC modems to Hayes.  

        Hayes has been shipping modems that provide 28,800 bit/s with 
230,400 bit/s throughput capability since last October with increased 
compression on OPTIMA 288 V.FC + FAX modems from 4:1 to 8:1.  This enhanced 
implementation of V.42bis allowed the serial port on OPTIMA 288 V.FC modems 
to run at 230,400 bit/s instead of 115,200 bit/s. allowing for significantly 
shorter transmission times for many forms of data in PCs and local area 
networks.

        Hayes complements its high-speed modems with Hayes ESP 
Communications Accelerator products, enhanced serial boards that support 
speeds up to 921,600 bit/s.  Hayes ESP maximizes throughput by implementing 
the Hayes COM-bic chip which supports 1K byte FIFO buffers, 16-bit bus 
interface and automatic flow control to overcome the receive overrun errors 
and throughput bottlenecks of popular UART chips such as the 16550.  The 
boards work with most standalone high-speed modems and ISDN terminal 
adapters, are fully compatible with Windows 3.1 communications software, and 
are available for ISA and Micro Channel Bus PCs.  Other drivers, including 
Novell AIO, OS/2 and Windows NT, will be available later this year.

        Hayes also plans to roll out modems supporting the V.34/V.FC 
modulation in the countries in which Hayes OPTIMA and ACCURA V.FC modems are 
currently offered.  Product will be available in these countries once 
approvals are received from the appropriate regulatory authority.  Upgrade 
procedures may vary on a country-by-country basis.

        Best known as the leader in microcomputer modems, Hayes develops, 
supplies and supports computer communications equipment and software for 
personal computers and computer communications networks.  The company 
distributes its product in more than 65 countries through a global network of 
authorized distributors, dealers, mass merchants, VARs, systems integrators 
and original equipment manufactures.
