Introduction

The PCL-743 series card both provide two RS-422/485 serial ports. Each port has a 16C550 UART with on-chip 16-byte FIFO buffer for reliable high speed serial I/O. The UART buffers data into 16-byte packets before putting it on the bus. This drastically reduces CPU load and avoids data loss when the system is busy and cannot process the interrupt quickly, and is especially useful for high speed serial I/O under Windows.
