在VB中MSComm1控件有发送但MSComm1_OnComm()一直不触发？急急

Question

Dim kk As Integer

Private Sub Form_Load()
If MSComm1.PortOpen = True Then MSComm1.PortOpen = False
MSComm1.CommPort = 8 '设置端口号
MSComm1.Settings = "38400,n,8,1" '设置波特率等
MSComm1.InBufferSize = 1 '设置接收器缓冲区大小
MSComm1.OutBufferSize = 1 '设置发送器缓冲区大小 '串口初始化
MSComm1.RThreshold = 1 '设置当当接收多少字符后触发oncomm事件
MSComm1.InputMode = 0 '设置输入寄存器接收数据的形式，0为文本、1为二进制形式
MSComm1.OutBufferCount = 0 '清除输出缓冲区的数据
MSComm1.InBufferCount = 0 '清除输出入缓冲区的数据
Timer1.Enabled = False
Timer2.Enabled = False
kk = 0
If strRW <> "" Then
Call FUN_FSSJ(strRW)
End If
End Sub
Private Function FUN_FSSJ(STR_RWSJ As String)
ReDim Sent(Len(strRW) / 2 - 1)
ReDim int_RWFS(Len(strRW) / 2)
Dim int_n As Integer
Dim Sent1() As Byte

For int_n = 0 To Len(strRW) / 2 - 1
int_RWFS(int_n) = Val("&h" & Mid(STR_RWSJ, int_n * 2 + 1, 2)) '将任务数据拆分成6B
Sent(int_n) = int_RWFS(int_n)
Next int_n
On Error GoTo FUN_FSSJ_ERROR
If MSComm1.PortOpen = False Then MSComm1.PortOpen = True
MSComm1.OutBufferCount = 0 '清空缓存
MSComm1.InBufferCount = 0
MSComm1.Output = Sent() '发送数据

Exit Function

On Error Resume Next

End Function

Private Sub Timer1_Timer()
If kk <= 2 Then

Else

Answer 1

但我做了以下2个(换算二进制为1010)这是否说明要改为:MSComm1.不对啊，MSComm1.Output 只能发送字符格式的 ，也就是说MSComm1.Output=
