APT HSS08 8 port buffered serial adapter       $299

APT Technology, Inc. is pleased to announce the  availability  of
the  HSS08  high  speed serial adapter board for the AT BUS.  The
HSS08 adapter board is implemented as  a  low  cost  single  card
offering  8  RS-232C  serial ports.  The ports are 100% IBM PC/AT
serial port compatible and each port includes all signals of  the
standard IBM PC/AT serial interface.

The HSS08 high speed serial adapter card was especially  designed
for use with UNIX based PC's and compatibles.

The HSS08 uses 8 16550A buffered UARTs which buffer incoming  and
outgoing  character  streams  to  substantially  reduce interrupt
overhead. The HSS08 has an 8 or 16 bit interface allowing  it  to
use  the  high  order  IRQ lines of the PC/AT,  and up to 4 HSS08
boards may be daisy chained onto the same IRQ line,  allowing  up
to 32 serial ports to operate off of a single IRQ.

Each port of the HSS08 can be  configured  to  support  XON/XOFF,
hardware,  or  no  handshaking.  The HSS08 correctly supports the
hardware handshaking modes of the Telebit Trailblazer+ modem  and
the HP Laserjet II printer.

The HSS08 also offers a PC-Compatibility mode which allows two of
the  ports to act identically to the standard PC/AT COM1 and COM2
serial ports.

The HSS08 may be used with standard serial port drivers,  or  the
user  may  use  the included driver to enable all the features of
the HSS08 board.  The HSS08 works with most standard releases  of
UNIX  for  the  PC  platform, and comes with a thorough manual to
help the novice  user  install  the  HSS08  and  connect  various
devices to it.

The HSS08 comes in either the OEM version for use  with  computer
cases  which  have  cutouts  in  the  back  for  the  serial port
connectors, or the standard version which includes a box to mount
the additional RS-232 connectors on the back of the computer.

The HSS08 is being introduced at a retail price of $299,
and includes a 30 day money-back guarentee.
