I've logged all my progress here Raspberry Pi and the USB to TTL Serial Cable on Mac (unfinished).
screen /dev/cu.PL2303-000013FA 115200
Here's the errors that I'm getting
- It just hangs with a empty terminal screen.
- It errors / flashes
Cannot open line '/dev/cu.PL2303-000013FA' for R/W: Resource busyand then lands on
Sorry, could not find a PTY.then I get the command line back with a printed
[screen is terminating]statement.
- If I run it with
sudo screen /dev/cu.PL2303-000013FA 115200I get a completly different error
/dev/cu.PL2303-000013FA: ioctl TIOCEXCL failed: Resource busy, then the blank terminal screen.
How do I resolve these issues, and get my raspberry pi working with the USB to TTL serial cable on OSX?
