16550 uart造句

• An example that is still of contemporary relevance can be found in the 16550 UART, whose derivatives are still in widespread use.
• The commands needed to control a 16550 UART are much different from the commands needed to control an FTDI serial port converter, but each hardware-specific device driver abstracts these details into the same ( or similar ) software interface.
• On Linux, 8250 / 16550 UART hardware serial ports are named / dev / ttyS *, USB adapters appear as / dev / ttyUSB * and various types of virtual serial ports do not necessarily have names starting with tty.
• However, many of the PS / 2's innovations, such as the 16550 UART ( serial port ), 1.44 MB 3.5-inch floppy disk format, 72-pin SIMMs, the VGA video standard, went on to become standards in the broader PC market.
• If you're going to use a 28.8-Kbps modem with an older 486-or 386-based PC, you may need to replace your existing serial port with one equipped with a 16550 UART . An older UART lacks the extended buffers necessary for seamless, speedy transmittal of compressed data.
• Interrupt coalescing is a common feature of modern network cards, but the technique dates back to early computer UARTs such as the 16550 UART chip used in the IBM PC's serial interface, at a time when even servicing the interrupt rates required by the low data rate serial data streams of the day was taxing for contemporary CPUs.
