Hi all, I am using the MSCOMM32 to interface with a machine in VFP5. I can receive data form reading the comm port. I just wonder will it "Clear" the input buffer once the read is issued(ie ThisForm.CommPort.Input). Because I am receiving some duplicate data. I just wonder what is the purpose of some of the comm properties, like ...HandShaking or ...InputLen or ...ParityReplace Is it neccessary to pay attention to these settings? Thanks!
