Beep bwoop bwoop beeep bwooooooooop

I've managed to figure out what my dial-up problem was. I should have guessed this earlier but I'd forgotten about some changes I made to my local phone plan which seemed to have done away with the 'disable call-wasting' feature or changed what you have to dial first to disable it. After taking that out of my modem dialing string, everything was just honky dory.

So I'm back online at home now and will stop silently bad mouthing Earthlink support off-line for my own stupidity.
