N E W S R E L E A S E APT TECHNOLOGY 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.
