Hi Antoon
the correct operation sequence to download from ft857 is:
- switch on the radio while pressing both <- > buttons to push it to 
clone mode
- prepare chirp for download selecting menu Radio - download from radio 
and setting the com port and radio type then press OK
- start send on the radio pressing C button
download (should) then start immediately and both radio and chirp show 
the operation via a progress bar.

For upload the sequence is:
- switch on the radio while pressing both <- > buttons to push it to 
clone mode
- prepare chirp for upload selecting menu Radio - Upload to radio and 
setting the com port (do not press Ok yet)
- start receive on the radio pressing A button
- press Ok in chirp dialog to start upload

You can find some info on the clone procedure at the end of ft857 
manual, chirp simulate the second radio: the receiving one when you 
download and the transmitting one when you upload.

I also must destroy the myth that the CAT speed have to be set in any 
way: in clone the ft857 the serial communication always take place at 
9600 and there's no menu that can influence the protocol in any way.
