ADSL / dailup set up

Hi, I have adsl set up in one place and I need dial up (form another provider in other) on my laptop. The only way I can switch between two at this moment is to reboot the computer. 1. Is it any way to swith between the two without rebooting? 2. Is there any program under windowmaker that will control the ADSl connection (turn it off and on - after discontecting)? Note: I tried tkpppoe , and command line adsl-start (setup) but I could not get it to work that is start ADSL (although ADSL is working fine when cable is conected while rebooting. Thanks for any help, Wojtek
