_x000D_ _x000D_ I want to auto detect devices connected to the COM ports of my computer. Being able to use the SerialPort class allows me to get the list of available COM ports easily. I want to iterate through them and poll(send a command) to each port and wait for a response. However it seems that most tutorials suggested to use the DataReceived event. I am lost at how to do a serial send followed by waiting for xx amount of seconds till I receive a response from the device.
