Thanks. You don't "configure" the specific terminal unless you're using it
with a specific program or as a login shell or whatever.

But I did find the answer here:

It seems that on the Mac, another device is created, the "cu.*" calling uni=
t
device . I can write to it with cat and it works.

"cat hex.bin > /dev/cu.usbmodem411" successfully sends the file and the
device is responding.


I should probably be using generic USB device driver for this stuff, but
it's so much easier just working with it in a UART type of way.
