Well finally figured out why I could not get the modems to work. Seems like there is enough limitation of audio bandwidth or noise that you can't use a V.34 modem on analog line with DSL superimposed. After editing register 56, my U.S. Robotics modem is now working.
I used a VT220 terminal and modem to call the local access line of Iglou.com. They run Shellaccess.com too. Each Iglou account comes with a Shellaccess account. That account is exactly that, a Unix shell account. So you can SSH you way to shellaccess.com and enjoy or….
What they don't advertise, you can call an Iglou analog access number and type shell after connecting. So I connected a modem to my VT220 terminal and with the appropriate Hayes comment (remember ATDT) called Iglou. Then I loaded a text web browser called Lynx.
I prefer the VT220
