如何在Linux中将二进制数据写入串行端口（RS232）设备文件中？
[英]How to write binary data into a serial port (RS232) device file in linux?
问题描述
I'm doing a project in linux for which i need to write binary data into the device file of serial port (RS232) port. 
我正在Linux中做一个项目，为此我需要将二进制数据写入串行端口（RS232）端口的设备文件中。 when i write the file into serial port (RS232), a RF transmitter connected to this port must send signal to RF receivers situated at different places. 当我将文件写入串行端口（RS232）时，连接到此端口的RF发送器必须将信号发送到位于不同位置的RF接收器。
The data to written is in a user created file.I have to just copy the data from that file and write into the device file whenever user wants(say a button click in java interface) 要写入的数据在用户创建的文件中。我只需要复制该文件中的数据并在用户需要时将其写入设备文件中（例如在Java界面中单击按钮）
I have googled but couldn't get much of the information and some i couldn't understand.What is the simplest way to do this using shell script.(C program will work too) 我已经在谷歌上搜索了，但是无法获得很多信息，有些我无法理解。使用shell脚本执行此操作的最简单方法是什么（C程序也可以工作）

From the command line, for example: 从命令行，例如：
cat file.bin > /dev/ttyPS0
-
file.binis binary file,file.bin是二进制文件， -
/dev/ttyPS0is device representing serial port./dev/ttyPS0是代表串行端口的设备。
Note: use stty to configure serial port appropriately. 注意：使用stty适当配置串行端口。
