Hello, sorry for ressending. I've forgot to say it's about MS Visual Basic. The MSComm control have the option to put the received bytes as text on a string variable (comInputModeText)or as binary data on a variant variable (comInputModeBinary). When using comInputModeBinary how can I retrieve the array of data (integers) received?
