Getting Connected
Linux
Command Line
I've used a couple of cli serial tools but settled on tio. In both cases though, it's easy to create configuration files to make connecting easy.
minicom
Available under most Linux distros.
example:
minicom -b 230400 -D /dev/ttyUSB0
tio
example:
tio --baudrate 230400 -flow hard /dev/ttyUSB0
See the instructions on Github for details of how to install or build tio.
Windows
A couple of options under Windows that I've used. Feel free to add your favourite. I don't have a favourite - both work equally well for me.
