stty serial port settings for parity not persistent

由 和自甴很熟 提交于 2020-01-16 16:50:28
问题 I have a netcore app that opens the serial port, and writes "parity error" on the console once a parity error gets detected. It works fine in Windows 10 but can't get it to work under Linux. My assumption is that the OS is not passing the parity error to netcore. For checking the port settings I run: stty -D /dev/ttyS0 -ignpar inpck then I run: stty -D /dev/ttyS0 -a and the settings seem to be properly set (-ignpar inpck) as expected. Then I run my netcore 3 app but parity error is not

Forcing raw serial mode in C - linux

问题 Not sure how to word the title, but what I'm trying to do is test my micro controller with my Linux PC to ensure data is correct. After hours of searching, I found out that the stty command can change how data is managed through the serial port and it turned out that by default if xon or xoff characters are received from the port, they don't get displayed. At first I thought my computer was too slow that I was losing characters at 57.6Kbps but that wasn't the case. Back in the day when I was

PhpSerial: No stty available — cant seem to get it working

问题 I'm working on a project which involves reading and writing to a Serial board, using the UART pins on my Raspberry Pi. However, I have hit a brick wall already. Any time I try use PhpSerial I always get the error: Fatal error: No stty available, unable to run. in /var/www/PHP-Serial/examples/PhpSerial.php on line 56 I've tried numerous configurations with the input: // First we must specify the device. This works on both linux and windows (if // your linux serial device is /dev/ttyS0 for COM1

google似乎把ADB输出的回车换行问题改掉了

google 改动内容在这儿，没有测试过，看起来没问题。 到目前位置，市面上所有的Android设备，都存在这个这个小问题： 在Linux/Mac上执行adb命令输出什么东西时，就算是二进制输出，那么LF(0x0a)字符会被转换成CR(0x0d) + LF。Windows上更可笑，会变成CR+CR+LF。 这个很好验证: 从Android上抓一个文件下来，例如/default.prop, 看看里面应该只有LF(0x0a)，而没有CR(0x0d)的。 adb pull /default.prop local_output_file1 然后在通过adb shell cat命令输出到本地，看看文件里是不是多了好多CR(0x0d)了。 adb shell cat /default.prop > local_output_file2 这个不是简单的因为Windows OS的缘故，Linux也出毛病。 解决方法一大堆，例如上述的pull，或者通过socket输出到PC。 其实还有方法可以完全不需要转换，也不需要pull,socket什么的。首先总结原因是两个： Android那边首先做了LF->CR+LF的转换。具体的在 ASOP 代码里有，adbd用了pty这东西来做输入输出。很古老的东西，没什么兴趣说， google最近改掉了 。 Windows OS这边的adb工具更额外做了一层LF-

What does “stty raw -echo” do on OS X

When I try: $ stty raw -echo on my Terminal (Bash on OS X 10.6). It does stringe things and it's like the terminal hang there. Then I lookup the manual: stty — set the options for a terminal device interface raw (-raw) If set, change the modes of the terminal so that no input or output processing is performed. If unset, change the modes of the terminal to some reasonable state that performs input and output processing. Note that since the terminal driver no longer has a single RAW bit, it is not possible to intuit what flags were set prior to setting raw. This means that unsetting raw may not
