$ curl -X POST http://pi:8000/devices/mcp/*/integer/129

==> invalid literal for int() with base 10: '*'.

delayed for major release - need new function mapping or REST handler refactor.

If anyone really needs portWrite() on digital devices, here is a small 
workaround that I use. Put the following code snippet into a custom server 
script:

#----------------------

import webiopi

@webiopi.macro
def mPortWrite(digitalDeviceName, value):
    digitalDevice = webiopi.deviceInstance(digitalDeviceName)
    if digitalDevice != None:
        return digitalDevice.portWrite(int(value))

#----------------------

It defines a macro that calls portWrite() for a digital device. The first 
parameter is the name of the digital device, the second one is the interger 
value to wite. This macro works only for digital devices, using names of other 
ones will cause an error.

REST path would be (using your example above):

..../macros/mPortWrite/mcp,129

Don't forget to include the script into your config file with the correct path 
to it.
