Look at the developers section of the twiki
http://chirp.danplanet.com/projects/chirp/wiki/Developers
Check out the code, then look at some of the drivers, like yaesu, etc.
Some use portmon, but I dont like it
personally.
Check out "free serial port monitor", which is free, but looks and feels almost exactly like eltima.
A note about usb serial. If your app is really interacting with a serial port (i.e., virtual com port), then you can probably see it with a serial port monitor.
Just fyi, While FTDI chips present serial "COM" ports (i.e., VCP drivers) to the OS which can be used by any application, some apps read/write data to the device using the D2XX api - which cannot be seen by serial port monitors hooking into the COM ports…
I have only seen a few apps do this. One of the more popular radio programming software suites out there does this ;)

Subject: [chirp_users] how to capture radio stream?
Hi guys,
I need an implementation for a FT-8000 but I may be the only one out there, so….
I thought I might be willing to invest some time into creating a driver as I need an excuse to fiddle with python anyway. It’s just another language, and been writing code for 20 years.
To that end, it would seem to me that
decoding/deciphering/analysis of the stream of bits and such is the real trick and mapping it to a structure that will work, ack, provide checksums etc. need some sort of analyzer widget for usb serial ports.
So what do you guys use to capture/reverse engineer what the radio is downloading to chirp, and how to figure out how to spit it back in the right format?? … is it published (I think not).
To start that discussion, what tools/techniques do you use/recommend to capture/deciper the kibbles n bits emitted from a target radio?
I tried a tool from eltima that seemed to work nicely until the trial expired, and I cant afford 150 bucks for a full version. Probably a boatload of other toolss out there than can help capture and break it up that will also allow one to send to fake acks etc.
