Linux - 与C的多串口通信(Linux - Multiple Serial Port Communication with C)

 我有一个带有多个串口的设备，我用嵌入式linux编程，我想同时和异步地通过这两个端口进行通信。 
 
 我知道如何写入一个串口，如： 
 
bytes_sent = write( fd, &(string[i]), 1 );
 
 但这只是一个串口 
 
 使用termios结构和c_cflags来区分端口？ 正如你所看到的那样有点模糊，我只是潜入水中并且用这种方式弄湿了，任何一般帮助指向我的方向都会有所帮助。 

I have a device with multiple serial ports that I am programming with embedded linux and I would like to communicate over these two ports simultaneously and asynchronously.
 
I know how to write to one serial port such as:
 
bytes_sent = write( fd, &(string[i]), 1 );
 
But that's to only one serial port
 
do I use the termios struct and the c_cflags to differentiate ports? As you can see it's a little vague, I'm just kind of diving in and getting my feet wet with this, any general help to point me vaguely in the right direction will help.
