YRRID INTRODUCES HIGH-SPEED SERIAL PORT FOR NeXT

Chapel Hill, N.C., August 3, 1992 - Yrrid Incorporated announces TTYDSP, a
high-speed serial port for the NeXT computer.  TTYDSP converts the Digital
Signal Processor (DSP) port on a NeXT computer into a third RS-232 serial
port, for use with a wide range of RS-232 peripherals including modems,
printers, and plotters.

"TTYDSP delivers the performance and reliability that today's high-speed
peripherals demand of a serial port," said Christopher Lloyd, Vice President
of Yrrid. "Because NeXT workstations have a built-in DSP port, our TTYDSP
product seemed a natural addition to the platform.  We think it's a perfect
and low-cost solution for NeXT customers who are not currently taking full
advantage of the DSP."

Using the processing power of the NeXT's DSP, TTYDSP drastically improves
system performance and communications reliability during high speed serial
data transfers.  As a result, it is ideal for UUCP sites, high speed dial-ins,
data collection, RS-232 printers, and plotters.

In addition, TTYDSP provides emulation of the NeXT serial port device,
maintaining compatibility with existing communications software.  TTYDSP can 
operate at a wide range of standard and non-standard baud rates up to 128,000
baud, and can sustain transfers with high-speed peripherals running at common 
rates such as 57,600 and 76,800 baud, which are unattainable with the standard 
serial port.

A TTYDSP compatible SLIP/PPP implementation - providing TCP/IP connectivity
through the DSP port - is planned for a late '92 release.

Pricing and availability:
TTYDSP costs $xxx.yy for a single user license and is available now from Yrrid.
Educational discounts are available.

Based in North Carolina, Yrrid Incorporated designs, implements and markets
products for the NeXT platform.
