I've been using mpfshell on my ubuntu machines for serial communications with ESP8266 HUZZAH Breakout boards, which has been working very well (many thanks, @wendlers!).

I'm now trying to help some students who use OS X machines. mpfshell installs via setup.py and appears to launch without errors through OS X terminal. However, it hangs on the open command when attempting to connect to the serial device.

Have any of you encountered this problem, and if so do you have installation recommendations or workarounds for OS X users?

I've used rshell on OSX with the pyboard.
If you pass in --buffer-size=32 and also specify the port (using --port /dev/name-of-serial-port) then it should also work with the ESP 8266.

If it also hangs on you then I'd like to hear about it.

I have gone over to using uftpd plus the regular serial REPL, works good for me.
