Java Mitutoyo串行通信数据值未更新

java serial-port

Java Mitutoyo串行通信数据值未更新,java,serial-port,serial-communication,Java,Serial Port,Serial Communication,我正在进行单元测试，以确保我从Mitutoyo仪表读取的数据值是正确的。我发送命令“GA00”并接收回数据值，然后发送命令“CR01”将第一个通道设置为0。然后，我再次发送命令“GA00”，查看通道1是否已更正回0，并且没有更改 但是，如果我重新启动测试，那么值将更改为我将其设置为的0，并且一切正常。重新启动将数据设置回0的应用程序/测试时会发生什么情况？如果我能弄明白，那么我就用我的代码来做，我会做得很好 谢谢你的帮助 我的代码： @Override public void run() {
