-
- The AT8+ and AT16+ are intelligent serial controllers for 80286, 80386, and
- 80486-based systems running UNIX or XENIX. They use an onboard 80186 processor
- with built-in DMA to manage up to sixteen RS-232 serial ports. The AT8+ and
- AT16+ offload the I/O overhead to their own dedicated processor, resulting in a
- maximum of 5 percent response time degradation (with 16 terminals). This
- combination of an I/O processor and main processor transforms the AT or
- 80386-based micro into a multi-user system running UNIX or XENIX. Up to four
- boards can be linked together to support up to 64 users
-
- Data transfers to and from the main processor are by direct memory access from
- any location under the control of the 80186. Each port is independently
- configurable for speed, parity, and word length. The onboard intelligence of
- the controllers with separate I/O buffers for each port eliminates any
- possibility of data loss at high speeds
-
- Microway's software drivers move character translation, line editing, echoing,
- and buffering from the main CPU to the 80186 I/O processor on the AT8+ and
- AT16+, making it possible to maintain single-user performance even with 16
- users connected.
