I am using COM6 and that converted to /dev/ttyS5 as shown below in the my log:
Converted COM Port COM6 to tty port /dev/ttyS5
I don't see that line in your case, I see the tty trying to use is /dev/ttyS-1, which means it pick it up your com port as zero COM0, and converted that to /dev/tty-1 by subtracting one from zero you end up with negative one, /dev/ttyS-1 is not valid port! If you are using COM2 then it should translate to /dev/ttyS1. Make sure there is a check mark in front on COM2 in the Arduino -> Tools -> Serial Port.
