You can use "mscomm control" to receive data from weight scale using rs232. The onComm event is used to receive data from serial port, and for more help follow the link:

Pls send feedback to me.

MSComm1.CommPort = 1
MSComm1.Settings = "9600,N,7,2"
MSComm1.InputMode = comInputModeText
MSComm1.InputLen = 0 'all buffer from port

MSComm1.NullDiscard = True
'Use in Sub MSComm_OnComm() all string conversion and port reading.

If you need more I can send more. Write me.
