I have a hd install of Knoppix 3.3. My hardware is a serial US Robotics modem. Up until last night, I was able to connect to the internet using Kppp. My problem started after I tried to use pon instead of Kppp. As root, I went through the pppconfig. I added my normal user to be able to use pon. After I typed in pon and hit enter, the modem did its intialize (ATZ) routine, then the dial tone, and at this point the pon quit. Now, I can not use my modem. Two lights (TR, CS) stay on and the SD and RD lights flicker. If I try using Kppp, I get the modem intialization, a dial tone , and then nothing.

The things I have tried so far is to restart my computer but that didn't cure it.. I tried to the mdem reset in the terminal part of Kppp setup but the modem does do the ATZ but then returns to the same light configuration. I have also used the Knoppix CD and was able to dial out using Kppp. Using the CD the modem acted normal.

What could have gone wrong after I used pon?
