New SCSI Product Announcement

[Neil Gorsuch]

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 and other 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 time than serial ports in the workstation
o   serial thruput of over 20K characters per second
o   saves ethernet bandwidth (much more precious than SCSI bandwidth)
o   uses less than 5% of SCSI bandwidth at 20K chars 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 two configurations:

SL41-1    4 RS232 serial, 1 Centronics parallel
SL81-1    8 RS232 serial, 1 Centronics parallel
