Hello,
I don't know what data the external device contains but the data is in intel hex format
I have to write a code to download it connecting rs232 using mscomm in vb6
pls help me
Thank You

What I have tried:

Private Sub open_Click()
MSComm1.comport=4
MSComm1.settings="115200,n,8,1"
MSComm1.PortOpen = True

End Sub

Private Sub download_Click()

dim data as variant
With CommonDialog1
.InitDir = App.Path
.FileName = ""
.Filter = "Hex File (*.hex)|*.hex"
.ShowSave

Do
ff = FreeFile
data=MSComm1.Input
Open .FileName For Output As #ff
Print #ff, data
Close #ff

Loop Until MSComm1.InBufferCount=0
End With


End Sub

"the data is in intel hex format"
If you still do not understand how this device presents its data, you need to study its documentation again.

Well how do you expect to operate it correctly if you do not have the most important information?

Are you going to update the internal firmware of a microcontroller?
