Introduction
PPCL-858 series interface cards provide eight RS-232 serial communication ports. Each port can be configured individually using on-board jumpers. PCL-858A/858B cards each have two 16C554 UARTs, which make serial I/O more reliable. The higher performance PCL858+ has two 16C654 UARTs. By buffering data into 64-byte packets before putting it on the bus, UARTs drastically reduce the CPU load. This makes the PCL-858+ especially suitable for high-speed serial I/O applications under multitasking environments and for applications involving high data rates.
