I'm writing some bare metal IBM PC software using DOSBox to test it, and I'd like to use the emulated serial port to output some debug info to the Linux host. What is the simplest way to do this?

Can I use the following config in DOSBox:
serial1=directserial realport:ttyS0

And on the Linux side:
screen /dev/ttyS0 9600
