Hello,
I've had the same problem with the python script. Hopefully I can add something meaningful here. I'm on Ubuntu 19.04. I have the FF5 repository cloned. This computer has Python 2.7.16-1, Python 3.7.3-1, and Python-Serial 3.4-4 installed.
From the terminal I tried the command (and got the reply):
jake:~/flashforth/shell$ python ff-shell.py
sys.exit cannot concatenate 'str' and 'int' objects
then I tried:
jake:~/flashforth/shell$ sudo python3 ff-shell.py
File "ff-shell.py", line 49
print "Port:"+config.port+" Speed:"+config.rate+" hw:"+str(config.hw)+" sw:"+str(config.sw)
^
(the arrow should point to the "P" in Port)
I have no clue what I'm doing when it comes to python. I'm just a casual hobbyist here. So far I've gotten the ff-shell.tcl to work, although, without the extra python script it lacks utility. edit removed bla bla bla....and figured out minicom's lineWrap feature...

*PS I also had to fix line 2535 in ff-p18.asm to build for a PIC18F26K22 yesterday :-)

Thanks for the reply Mikael. I'm sorry that I'm a bit slow to figure this out. In retrospect it seems quite obvious that I should try "-h" as an argument.
I haven't looked into why my computer doesn't like connecting hardware to /dev/ttyACM0, but it usually works if I use ttyUSB0, although the port numbers change sequentially as more hardware is plugged into the port. I'm just accustomed to looking up the port with $ dmesg | grep ttyUSB. It's probably a badly configured dialout group permissions type of problem. Now that I have an idea of what the python script is looking for, I think this is why the defaults didn't work. It worked perfectly with:
$ python /flashforth/shell/ff-shell.py -p /dev/ttyUSB0 -s 38400
That connected right away through a CH340G breakout and a PIC18F46K22 I received yesterday and just tested.
Thanks for all the effort you put into creating and sharing this project with people like me. I found out about this project from 0033mer on YouTube. This is my first adventure into FORTH.
Thanks again.

M.,
Howdy!
Always enjoy working with Flashforth, thanks for everyone's hard work!
Simple error when I experiment with the Python shell, (2.7.9 python, ubuntu 15.04)
"sys.exit cannot concatenate 'str' and 'int' objects"
Any insight on this available?
Thanks,
R.
So what did you do before the error ?

The shell only works with python2.
Try giving some argument to the shell.
About minicom
By default it does not wrap lines automatically.
ctrl-A Z R
enables the line wrap and you will see all the words.
