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.
