Receiving data on serial port not doing as expected

[roxydogg]

Most definitely but since you did not show any code all we could do is guess. most likely you are not writing to the file correctly to get the output you want and that is the source of your issue

Here's the code you asked for
Note that the text1 box shows the complete string all on one line
but the file has each letter on a new line.

Private Sub MSComm1_OnComm()
	Dim InBuffer as String
	Dim bytesIn as Integer
	Dim idx as Integer
	
	bytesIn = MSComm1.InBufferCount
	
	InBuffer = MSComm1.Input
	
	Sleep 500

	me.text1.text = InBuffer

	call Write_log_file(InBuffer)
	
End Sub


public Sub write_log_file(inString as String)
	Print #fhandle, inString
End Sub

Private Sub Form_Load()
	MSComm1.CommPort = 1
	MSComm1.Settings = "9600,n,8,1"
	MSComm1.PortOpen = True
	MSComm1.RThreshold = 1
End Sub
