Introduction

The PCL-849 cards provide four individually configurable RS-232 serial communication ports. PCL-849A, PCL-849B and PCL-849L have a 16C554 UART which makes serial I/O

more reliable, while the higher performance PCL-849+ has a 16C654 UART. By buffering data into 64-byte packets before putting it on the bus, UARTs drastically reduce the CPU

load. This makes the PCL-849+ especially suitable for high speed serial I/O applications under multitasking environments.

PCL-849 cards support two operating modes: standard mode and enhanced mode. In enhanced mode, the address for all four ports can be set automatically. PCL-849 cards also

support either shared IRQ or independent IRQ functions. When an on-board interrupt occurs, the interrupt status register (vector address) indicates which port generated it. The shared

interrupt can be set to most common (extended) AT interrupts. This simplifies programming, speeds up interrupt processing and frees up interrupts for other devices.
