从UNIX命令行发送字节到串行端口？ [英] Sending bytes to serial port from UNIX command line?

问题描述

我想使用命令行将字节流发送到串行端口。这可能吗？我的串行端口在Mac上的 /dev/cu.usbserial-A700dYoR 中。例如，如果我想向该串行端口发送整数50或字符串 data，我该怎么做？

我对UNIX的了解非常有限。

解决方案

 ＃！/ bin / bash 
 
＃端口设置
 stty -F /dev/cu.usbserial-A700dYoR原始速度9600 
 
 echo'Hello'> /dev/cu.usbserial-A700dYoR 
  

或类似的东西，如果我没记错的话...几年。您可能必须要 sudo 才能起作用...

这是在发送文本...不是二进制...发送数字50作为文本

  echo'50'> /dev/cu.usbserial-A700dYoR 
  

将其作为二进制整数发送会更加困难。 / p>

i would like to send a stream of bytes to a serial port using the command line. is this possible? my serial port is at /dev/cu.usbserial-A700dYoR on my Mac. for example, if i wanted to send the integer 50 or the string "data" to that serial port, how can i do that?

my knowledge of UNIX is very limited.

解决方案

#!/bin/bash

# Port setting
stty -F /dev/cu.usbserial-A700dYoR raw speed 9600

echo 'Hello' > /dev/cu.usbserial-A700dYoR

or something like that if I remember correctly... Been a few years. You will probably have to be sudo for it to work...

This is sending text... not binary.. to send the number 50 as text

echo '50' > /dev/cu.usbserial-A700dYoR

to send it as a binary integer would be more difficult.
