Just installed WinXP as part of Dual Boot system with Win ME. When using my dial up through WinME (USR External Serial Modem)...No problems. Then when I go to XP, even if I shut down between times, and try to start my dial Up, I get a message that the Serial port that my modem is on is "In Use", and it wont let me dial out. If I then go back to Win ME....No problems ??? Please help me with this as I am a complete newbie with Win XP.
