I used to work with scales and mscomm.



To aid us we had written a Scale Emulator in VFP. To use it you need a COM cable and 2 ports. The Scale Emu sits on one port and sends its output and the MSComm sits on the other port and accepts input.



The Scale EMU is configurable and the strings are stored in a table.



The other VFP form sits on the other COM port and waits for input. It too is configurable and works for continuous input, also with settings for KG, decimal place etc.



It was an essential tool. The COM cable is plugged into the 2 ports and The Scale EMU sends the string out one and the FOrm receives into the other.
