System wide configuration file is "avrdude.conf"
Using Port : COM3
Using Programmer : wiring
Overriding Baud Rate : 115200
avrdude: ser_open(): can't open device "\\.\COM3": Access is denied.

Any help would be appreciated. Attached file shows my Device Manager.
Another program is accessing the COM port simultaneously... do you have the Terminal (termite) open too?
@pbruno3 Thanks, yes the BruControl application was running with a digital output to the COM port....duh.
