Dialing into Earthlink.net. Using Caldera on an AMD K-6 233, external modem. Have tried using ppp-on and pppd with a logon script. Appears to work, I get the: ppp0 <--> /dev/ttyS0, and then hangs up for no apparent reason: Hangup (SIGHUP). Is the hangup originating from them or my PC? Is the loopback preventing the DHCP from working, how do I shut it off if so?
