Not sure if this has been requested as of yet, but would it be possible to get some sort of virtual modem that you could use to preconfigure a modem then export the config file to import into a new modem.

For instance at the moment I need to reconfigure a clients current modem for work that will take place in a month or so. The configuration is going to take me a few hours to make sure every thing is correct. At the moment I can't do it till the day the work is meant to take place. If there was some sort of virtual modem that was available through Draytek's site or that you could download and use locally on your own machine that would make life easier as I could have done the work before hand and on the day spend a few min uploading the config file and testing it.
