How to Fix CR/LF Transmission Issues Between MS Excel VBA and STM32 via Serial?
yeh, sure..you can try this. Instead of relying on the Datastream add-in, use VBA to manually append Chr(13) (CR) or Chr(10) (LF) to your message: 
Dim msg As String
msg = "YourMessage" & Chr(13) & Chr(10)
SerialPort.Write msg
Dim msg As String
msg = "YourMessage" & Chr(13) & Chr(10)
SerialPort.Write msg
