换成Encoding.ASCII 试试
你不用程序的情况能不能用TAB切换焦点。如果这样不行的话你用程序控件是没用的。
或都直接对第二个编辑框发送消息。

我处理这个问题的大概过程，当程序响应DataReceived时：
Private Sub MyCOMM_DataReceived(ByVal sender As Object, ByVal e As
System.IO.Ports.SerialDataReceivedEventArgs) Handles MyCOMM.DataReceived
If IsClosing Then Exit Sub '如果界面正在关闭串口则退出过程
Try
IsListenning = True'设置正在读取标记，供界面操作判断
Wait(150)'等待150毫秒
Dim n As Long = MyCOMM.BytesToRead
Dim buf(n - 1) As Byte
Try
MyCOMM.Read(buf, 0, n)
Catch ex As Exception
MsgBox("接收短信出错", "COMPort.DataReceived")
Throw New System.Exception(ex.Message)
Finally
IsListenning = False'无论接收数据成功与否，都关闭正在读取标记
End Try
MyCOMM.Close()
MyCOMM.Open()
'Do SomeThing
Catch ex As Exception
MyCOMM.Close()
MyCOMM.Open()
End Try
End Sub
Protected Sub Wait(ByVal miliseconds As Integer)
Dim tmpNow As Date = Now
While Now.Subtract(tmpNow).Milliseconds miliseconds
Application.DoEvents()
End While
End Sub
希望能帮的上忙
