RS232通讯 VB.NET 语句编写
例：发送命令：focusoffset -w -w 12接收信息：wide focus offset value written in eeprom is 0x12 (18 in decimal)。。。长度不定。
代码怎么编写？

--------------------编程问答--------------------
Delegate Sub CallBack(ByVal data As String)
Private sp As SerialPort
Private Sub ConnPort()
sp = New SerialPort("com2", 9600)
AddHandler sp.DataReceived, AddressOf SerialPort_DataReceived
sp.DataBits = 8
sp.Parity = Parity.None
sp.StopBits = 1
sp.Open()
sp.Write("test")
End Sub
Private Sub GetData(ByVal data As String)
MessageBox.Show(data)
End Sub
Private Sub SerialPort_DataReceived(ByVal o As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs)
Dim data As String = sp.ReadExisting()
Dim cb As New CallBack(AddressOf GetData)
Invoke(cb, data)
End Sub
代码有测试，会丢失数据，但用超级终端测试OK,参考附图。

顶二楼吧，那样写应该就没有什么问题了。串口相对还是好操作的

操作是简单，丢数据就麻烦。--------------------编程问答-------------------- 怎么让接受速度加快？貌似有些数据丢失，求解。
补充：.NET技术 , VB.NET
