echo and tty issue

[Philip Yao]

I am trying to echo like so:

echo -ne “hello” > try.mydevice

and I believe I have the correct baud rate settings. I can screen into my
tty device just fine and everything works on a Linux computer.

I found some old stackexchange post mention some problem with echo and
macports, so I’m just making sure.

Thanks
