I am trying to read data from serial port. The port being used is COM1. I am getting the following error :
??? Error using ==> serial.fopen at 72Port: COM1 is not available. Available ports: COM8, COM17, COM19.Use INSTRFIND to determine if other instrument objects are connected to the requested device.
Please suggest possible reasons.
