I don't think there is a way inside the Reflection client. I tried myself. The good news is though, it uses telnet which can be done through pretty much any program imaginable.
trial run:
go to start->run , type CMD and hit enter
In the command window type telnet <your adp server ip> <the port you want to use>
you should get a login prompt.
Now this is assuming the ADP server will accept incoming telnet requests on a different port. If that hasn't been changed it won't work. Also, telnet through the command window is slooow.
