I got a call from someone who wanted me to come out and set up his dial-up for AT&T and give the computer a tune-up. He lives too from from civilization and can't get DSL or cable. He doesn't want to pay for satellite. I had to call AT&T because the numbers that their software had were no good. I talked to customer support I got a new working number. I created a new connection under network connections so I'm not using the software they sent. It works perfectly.
The problem is that after I disconnect, the modem holds the line open. I have to unplug the cable for a moment to get it to hangup. He told me that 3 years ago or so he had dial-up with another service and did not have this problem. My modem skills are a bit dusty because I haven't used dial-up in years.
The computer is an old Dell with XP.
Anyone have an idea of what's going on? I'm going back out this week to tie up a few loose ends. I've looked around and really haven't seen anything useful other than adding something to the AT Command set.
Any help would be greatly appreciated
