Re: [Flashforth-devel] ff-shell3.py question

[Mikael N. <mik...@fl...>]

So I added the close() and open() to serial_open(config) and it works 
just fine on linux, maybe then also on OSX.
Like this:

   try:
     config.ser = serial.Serial(config.port, config.rate, timeout=0.5, 
writeTimeout=1.0, rtscts=config.hw, xonxoff=config.sw)
     config.ser.close()
     config.ser.open()

Does that help ?
