Mscomm设置

单片机与PC机通信的,就是PC机显示的问题.现在程序如下: Private Sub Form_Load() MSComm1.Settings = "9600,n,8,1" '设置波特率和发送字符格式 MSComm1.CommPort = 1    '设置通讯串口 MSComm1.InputLen = 0        '设置或返回一次从接收缓冲区中读取字节数，0表示一次读取所有数据 MSComm1.InBufferSize = 1024 MSComm1.InBufferCount = 0 MSComm1.OutBufferSize = 1024 MSComm1.OutBufferCount = 0 MSComm1.RThreshold = 1 MSComm1.SThreshold = 1 If MSComm1.PortOpen = False Then MSComm1.PortOpen = True End If End Sub Private Sub Cmdsend_Click() Timer1.Enabled = True 'Varbuffet = "S" ' MSComm1.Output = Varbuffet End Sub Private Sub Timer1_Timer() Varbuffet = "S" MSComm1.Output = Varbuffet Timer1.Enabled = False End Sub 'Private Sub Timer1_Timer() 'Outputsignal = Str(Textsend.Text)                        '向单片机发送数据 'Temp(1) = CByte(Outputsignal) 'Varbuffer = Temp 'MSComml.Output = Varbuffer 'MSComml.Output = Str(Textsend.Text) 'Timer1.Enabled = False 'End Sub Private Sub MSComm1_OnComm() Select Case MSComm1.CommEvent        '设置oncomm事件，读取片机内存的值 Case comEvReceive Inputsignal = MSComm1.Input TextReceive.Text = Asc(Inputsignal)            '单片机内存的值用textbox显示出 Case Else End Select End Sub Private Sub Cmdquit_Click() 'MSComml.PortOpen = Fasle Unload Me End Sub 单片机发送 0 1 2 3 让PC机显示,怎样才能显示0123(一起显示),而不是 0 1 2 3覆盖着显示.现在是显示0,在显示1, 显示2,显示3 而不是0123一起显示.谢谢!
