I am working a project with an arduino mega 2560. I have Installed the drivers and they work fine but when I tried to test the board with a servo sweep program from the arduino site, nothing happened. I get the error that says serial port COM1 not found. I go to tools to fix this and the serial port option is greyed out and I cannot access it. There is nothing attached to the arduino except the usb cable. Therefore I do not know how to upload any programs to the board. Thanks!
