TypeError in AJAX POST passed to PySerial

[spogs]

When I do the following:

    s= serial.Serial('/dev/',9600)
# or set a function and pass via command line
    s= serial.Serial(arg1,9600)

The code executes without any error.
But, when I use AJAX and POST the parameters to the script

def index(req):
    info = req.form
    sys.stderr = sys.stdout
    s= serial.Serial(info['device'],9600)

An error occurs:

return '/dev/ttyS%d' % port

TypeError: %d format: a number is required, not StringField

I have no idea why it is doing this, I checked the POST parameters passed by printing them and they are coming through.

Any suggestions would be greatly appreciated.

Thanks,

Hi Spog,

I think you sent a message to the wrong forum, this forum is related to python for S60 devices

BUT, the error is clear:

return '/dev/ttyS%d' % port
TypeError: %d format: a number is required, not StringField

Port has been used as string and it must be a number, see the %d at first line. Please, check your code and how you set the serial port number.
