有没有牛人帮忙看下这段程序问题出在哪儿吗？
Private Sub Form_Load()
MSComm.CommPort = 1
MSComm.Settings = "9600,N,8,1"
MSComm.InputLen = 0
MSComm.InBufferSize = 1024
MSComm.OutBufferSize = 512
MSComm.PortOpen = True
MSComm.SThreshold = 0
MSComm.RThreshold = 4
MSComm.InBufferCount = 0
MSComm.OutBufferCount = 0
Text_RECV.Text = ""
End Sub
调试的时候这部分有问题，Private Sub Form_Load()变黄，不知道什么原因
