- 在通讯中,为了保证行运安全可靠,标准的串行口必须具有许多握手信号和 状态信息。这是因为通兜母鞲黾扑慊鶦PU速度不一样(这会导致“错帧”)以 及发送机发送数据速度比接收机接收速度快(这会导致“过冲”)。为解决这个 问题,我们采用一个简单的握手信号,即发送机每次仅发送半个字节(低4位) 的数据,而另外半个字节(高4位)则用来传送信息。我们可以对信息位(高4位) 进行如下简单的编码: 0H:发送的是新的半个字节数据 1H:重新发送上次传送错误的数据 2H:文件名结

RS232_Port
- 详细描述了RS232物理细节。 典型地,串口用于ASCII码字符的传输。通信使用3根线完成:(1)地线,(2)发送,(3)接收。由于串口通信是异步的,端口能够在一根线上发送数据同时在另一根线上接收数据。其他线用于握手,但是不是必须的。-A detailed descr iption of the physical details of the RS232. Typically, serial code for the ASCII character transmission. 3 li

chuankoutongxin
- 串口通信的概念非常简单,串口按位(bit)发送和接收字节。尽管比按字节(byte)的并行通信慢,但是串口可以在使用一根线发送数据的同时用另一根线接收数据。它很简单并且能够实现远距离通信。比如IEEE488定义并行通行状态时,规定设备线总常不得超过20米,并且任意两个设备间的长度不得超过2米;而对于串口而言,长度可达1200米。典型地,串口用于ASCII码字符的传输。通信使用3根线完成:(1)地线,(2)发送,(3)接收。由于串口通信是异步的,端口能够在一根线上发送数据同时在另一根线上接收数据。其
