PCL-858a and PCL-858b each have two 16c554 uarts, which make serial i/o more reliable. the PCL-858 cards support automatic addressing for all eight ports. all channels share the same interrupt (irq), and an interrupt status register can be used to determine the interrupt source. when an onboard 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.
