I want to transfer a number from java program which is on laptop (means there is no rs232 protocol pin is provided) to a pic microcontroller(where essentially I have to used rs232) .Therefore here I require usb /rsr232 converter. 我想从笔记本电脑上的java程序传输一个数字（意味着没有提供rs232协议引脚）到pic微控制器（基本上我必须使用rs232）。因此我需要usb / rsr232转换器。 Which Java library should I use ? 我应该使用哪个Java库？ Will it work with javax.comm library? 它可以与javax.comm库一起使用吗？

The answer is it depends on the USB/RS232 converter you are using. 答案是它取决于您使用的USB / RS232转换器。 Most that I have used will expose the serial port as a virtual com port device on your operating system (see page 8 of this PDF document ). 我使用的大部分内容都会将串行端口暴露为操作系统上的虚拟COM端口设备（请参阅本PDF文档的第8页）。 If that's the case, javax.comm will work fine. 如果是这样， javax.comm将正常工作。 If not, you will have to use a proprietary API for the hardware which should be provided by the manufacturer. 如果没有，您将不得不使用专有的API来为制造商提供的硬件。 If you have hardware like this, I would strongly recommend replacing it with a class-compatible USB device. 如果你有这样的硬件，我强烈建议用类兼容的USB设备替换它。
