我实际上是在尝试从中获取数据,port1
但Invalid port number
生成了错误。
代码是:
Private Sub Command1_Click()
MsgBox ("The port is open " & MSComm1.PortOpen)
If (MSComm1.PortOpen = False) Then
MSComm1.PortOpen = True
End If
Command1.Enabled = False
Command2.Enabled = True
End Sub
Private Sub Command2_Click()
If (MSComm1.PortOpen = True) Then
MSComm1.PortOpen = False
End If
Command1.Enabled = True
Command2.Enabled = False
End Sub
Private Sub Form_Load()
With MSComm1
.CommPort = 1
.RThreshold = 1
.RTSEnable = True
.Settings = "9600,N,8,1"
.InputLen = 127
.SThreshold = 1
End With
End Sub
Private Sub Form_Unload(Cancel As Integer)
If (MSComm1.PortOpen = True) Then
MSComm1.PortOpen = False
End If
End Sub
Private Sub MSComm1_OnComm()
Dim Buffer As String
Select Case MSComm1.CommEvent
Case comEvReceive
'Text1.Text = " "
Buffer = MSComm1.Input
Text1.Text = Text1.Text & Buffer
End Select
End Sub
