[Other resource] my_com2007 DL : 0: 常见的接口：1、并行接口（每一次传送一个字或字节的全部代码）INTEL 8255，MC6820，Z80＿PIO，传送的距离比较近。 2、串行接口：数据和控制信息是一位一位串行地传送下去，距离比较远，通常COM1使用是9针D形连接器，COM2使用是老式的DB25针连接器， 3、磁盘接口（1）IDE接口，集成驱动器电子部件，不支持DMA数据传送，只使用标准的PCI/O端口指令来传送所有的命令，状态等（2）EIDE接口， 4、SCSI接口。具有多任务接口，具有总线仲裁功能。按同步或异步方式传输数据，可分单端和差分传送方式，是智能化设备。 5、USB接口。 -common interface : 1. Parallel Interface (each carrier or a byte characters of all code) INTEL 8255, MC6820, Z80_PIO, transmission distance closer. 2, Serial Interface : data and control information is a one on serial transmission distance is far, usually COM1 use of 9-pin D-connector, COM2 use of old needles DB25 connector, 3, Disk Interface (1) IDE interface, integrated actuator electronic components, not to support DMA data transfer, to use only standard PCI / O ports directive to transmit all the orders, status, etc. (2) EIDE interfaces, 4, SCSI interface. Multi-task interface with bus arbitration function. By synchronous or asynchronous transmission of data can be divided into single-ended and differential transmission, intelligent equipment. 5, USB interface.
