Did you ever want to add serial ports to your "non-expandible"
workstation without having to use network protocols such as TCP to
access them?  Ever wanted to add a low cost printer but found out that
they only have a Centronics parallel interface, or wanted to add a
high speed laser printer but couldn't because serial ports couldn't
handle the required thruput?  Ever needed support of ALL modem and
control signal lines to connect a modem?  Uninet Peripherals has the
answer to these questions.  It's called SLAT.

Use the SCSI bus to transparently add 4 or 8 RS232 serial ports and a
Centronics parallel interface to these and other machines: Sun 3,
Sun 4 including Sparcstation, Decstation, Vaxstation, Macintosh.
SLAT offers these features:

o   serial and parallel ports supported through the standard tty driver
o   no new drivers required, no kernel rebuilds necessary
o   uses only 1 SCSI address
o   co-exists peacefully with other SCSI devices such as disks and tapes
o   supports all modem control signals
o   supports input/output xon/xoff throttling at the SLAT level
o   uses less CPU overhead than serial ports in the workstation
o   serial thruput of over 20K characters per second
o   SCSI xfer rate over 2.5 Mbytes per second
o   uart baud rates to 76.8K and beyond
o   support of arbitrary baud rates (can you say MIDI ?)

The SLAT can be ordered in 2 configurations:

SL41-1    4 RS232 serial, 1 Centronics parallel     $900
SL81-1    8 RS232 serial, 1 Centronics parallel    $1600

Host software media, documentation, and a license costs $75.  Only a
single software license is needed per site.  Various SCSI cables are
available for $85 each.  The serial ports use RJ45 connectors.  The
parallel port uses a DB25 connector.  Serial and parallel port cables
are available through most computer stores.
