SerialPort version: 5.x
Operating System and Hardware Platform: OSX

Summary of Problem

OSX SerialPort.list returns /dev/cu.xxx ports but tries to lock them by default and they cannot be locked. Only /dev/tty.xxx ports can be locked.

The code that find's the path of the port.

Thanks to #1070 and @lynndylanhurley for the report!

Issue with serialport.list on Mac - Node Webkit #1110

Closed

I saw the comments about passing {lock:false} into the open options, but is there any workaround that permits the use of the SerialPort.list

If not, is there a way to catch or avoid this error when using SerialPort.list, even if we can't properly return the port?

@dcyoung this issue is requesting someone make serialport list do what you ask

I cannot find a way to do this in c++. I'm having a hard time finding docs on the functions we use. Maybe a string replace from /dev/cu. to /dev/tty. is in order, unless anyone has better ideas. =|

Figured it out, will have the tty ports in the next release.

For the record, tty's are `DialinDevice`s and cu's are `CalloutDevice`s

Thanks to @kishinmanglani for helping me solve this!

The closest we could come to docs. https://opensource.apple.com/source/IOSerialFamily/IOSerialFamily-7/IOSerialFamily.kmodproj/IOSerialKeys.h
