Problem with SerialPort

Question

I\'m working with SerialPort to communicate (read only) with barcode reader.

I\'ve installed driver to operate with the reader as if it was connected via Com-port,

Answer 1

I've had the same experience. Although it is not advised, you can unplug and plugin a serial device to an actual serial port and the communication will begin again. A USB serial port doesn't work this way. I've also had the problem of the USB serial port not appearing as an available port by the SerialPort.GetPortNames() method until after the virtual serial port is instantiated by the software.
