怎么才能在VEE中重新建立串行连接？

我正在开发一个使用直接IO控制到串行设备的测试。
我配置了串口，可以从UUT发送命令和读取数据。
我遇到的问题是，当我关闭UUT（我在测试期间必须做几次）时，它不会重新连接到串口。
我必须关闭并重新启动我的VEE程序才能建立连接。
有没有办法在VEE中重新建立串行连接。

  I'm developing a test using direct IO controll to a serial device. I have the serial port configured and can send commands and read data back from the UUT. The problem I have is that when I power down the UUT (which I have to do several times during the test) it doesn't re-connect to the serial port. I have to shutdown and restart my VEE program to establish the connection. Is there a way to re-establish a serial connection in VEE.
