Okay, so they're trying to get it working, and of course I get called as tech support. With my sister's cell phone, they can talk to me (well, more on that later) while they're trying to dial up/are dialed up. But, the cell phone connection wasn't very good and I couldn't hear my sister worth a crap. As she says the battery is dying, I realize that they're online now, and we can use ICQ. Then I remember VNC, and figure that if I can get them on VNC, I can run the computer for them.
So, I get ICQ to send them the file with the VNC installer, and they get it installed. I take over the computer, and fix my sister's goofs. For probably never having to use a shared-cursor chat before, I think she did very well when I opened Notepad to chat with them. (Voice connection was out of the question, as the remote computer is a 486DX2/66... yes, there's still at least one of those on the Internet.)
But it's all fixed now. Hallelujah for VNC!
