[chirp_devel] adding FT-65 support, devloping on mac

[emb sys dev]

Hello chirp devs,

My name is Darryl and I would like to add support for the Yaesu FT-65.

My background: embedded operating systems including WinMo, Linux, and
vxWorks, various RTOS, bare metal firmware, boot loaders, device
drivers.  Mostly C, C++, and Java. I have a few months of practical
experience with Python, but am still a bit of a noob at certain
things.  No problem following procedural code, objects, inheritance,
etc.

The obvious strategy is to copy and edit ft60.py and work it forward.

Thus far I have:
1) cloned the repository
2) copied ft60.py to ft65.py, s/60/65/g, changed up/download help strings.
3) diffed the new file into the chirp installation under /Applications
4) ran app, chose download from radio, chose ft65 from the menu.
5)  download hangs (pretty much expected)

ASK:
I need some help with a couple of things:

1) Need a serial port sniffer for mac.  I have a USB protocol analyzer
but due to the single-byte polling used, I get a capture buffer line
per byte, which is a lot to wade through. I googled but didn't find
anything free for OSX.  If there's an open source solution let me
know, I have built stuff with brew from time to time.

2) what cmd line fu do I need to launch chirp from terminal?  I have
PyCharm professional, and like Eclipse, it requires a Debug/Run
configuration.
