In trying to set up PPP, I've been unable to fix this problem:
I dial into the ISP (and I've tried 2 different ones - same results) with minicom, then I quit without a modem reset, and type "pppd -d -detach /dev/modem &"
at this point the modem always just hangs up.
If I look in /var/log/messages, I always get a "serial device looped back" message right after ppp connects. All the docs that I've found assume a problem with a script or something like that, but I'm not using one yet! help?
