Problem uploading to board

Sketch uses 6600 bytes (20%) of program storage space. Maximum is 32256 bytes. Global variables use 486 bytes (23%) of dynamic memory, leaving 1562 bytes for local variables. Maximum is 2048 bytes. avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.

Getting this message when trying to upload to my uno as well as has a constantly flashing red on the L led.
