串口通讯错误 #176

我在使用 UGS 时遇到了问题。似乎有一个沟通问题，一些 g 代码被跳过，并且在作品被毁后不得不中止几个工作。
我在 Windows7 64 位和 Java 32 位版本 7 更新 60 中运行。
它随机发生，有时在开始时发生，有时在 1000 行完成后发生。
我不怀疑硬件问题，因为 grbl 中包含的“stream.py”在 55k 行的工作中运行得很好。

我在控制台中得到的错误是：（
“O recurso pedido esta a ser utilizado。”意思是“请求的资源正在使用中”）

Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
Error 0xaa at /home/bob/foo/rxtx-devel/build/../src/termios.c(1278): O recurso pedido esta a ser utilizado.
