[newbie] I can't get connected to internet

[Mauricio Castro]

I have a pctel modem installed on my computer with mandrake 7.0.
When dialing up the internet number everithing is going fine, but when
it says "starting pppd" it hangs up. I dont know if is the modem or the
drivers, i'm very newbie, like 2 months of xperience.
