Hi everybody
I want to use the serial port class in the .Net Framework to access COM-port devices.
I am presently able to open a port and send some data over the port as follows:
#light open System.IO.Ports let availablePortsArray = SerialPort.GetPortNames let s1 = new SerialPort ("COM5",9600) if s1.IsOpen then print_endline "Port is Open" s1.Open() s1.Write "0xFF" s1.Write "Hello World" s1.Close() if s1.IsOpen then print_endline "Port is Open" //end of codeHow do I access the array "availablePortsArray" to see what ports are
available for the current computer?
Kind Regards
