            內(nèi)容介紹
          the pcl-740 offers a versatile range of high speed interfacing options. you can switch its single port between the popular rs-232, long distance rs-422, multi-dr-op rs-485, or noise-resistant current-loop. the card"s 16c550 uart has an on-chip 16-byte fifo buffer for faster and more reliable communication, especially under windows. the card has two 16c550 uarts with on-chip 16-byte fifo buffers. the uarts buffer 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.
