I use kppp in KNOPPIX to dial up to my ISP and log in using terminal mode (as I have to input the account and password in terminal mode). After log in, I can browse the web pages using mozilla but just for a few minutes and after that there is no response from mozilla. If I disconnect and reconnect using kppp, I can go through the web pages for another few minutes and then no response again. I use an external modem Lemel MD-56K and connect it to com1. Can anyone help me to solve this problem please. Thanks a lot!
