On I just installed mini pro on OS X 10.11.6 And am getting "Error opening device".

Is there something I am missing?

I'm not mac os user so i can't say what is wrong there. Maybe this is something related to device access permission? try to run minipro as superuser if you can.

Great! if you want and have time please test my fork here: https://gitlab.com/radiomanV/minipro
I have added some features wanted by users. I have not submitted yet an merge request (i want to implement something new).
Thanks.

Hi,

I will test it.

Can you use intel hex files?

Can you program avr fuses?

The hex files are not supported yet directly but with the help of miniprohex.
Regarding to avr fuses yes you can program them.

How do you program the fuses?

Is there a wiki?

You must supply a config file. Unfortunately this software have a bug reading or writing fuse config files. This is why i said to test my fork; i fixed this bug.
So to program fuses first you should read them like this: 

minipro -p "atmega8" -r ./fuses.conf -c config

Then look at the fuses.conf file format and change the desired fuse value.
When you want to write the fuses back you should use the -e flag to skip erasing (if you omit it the avr will be erased first and then fuses will be programmed leaving the memory blank which is not desired).
So a write should look like this:

minipro -p "atmega8" -w somefile.bin -c code

and after that fuses: 

minipro -p "atmega8" -w fuses.conf -c config -e

You can combine the two commands with &&

@radiomanV Could you submit a merge request based on what you have now that works?

This issue had me very confused as to exactly what the problem was. #135 finally clued me in and the problem is now fixed: garbage was being written to the terminal when it was partially opened for pager output and then minipro_open() aborted because no programmer was attached. So the terminal was left in an inconsistent state.
