Well, I was able to fix the problem. See, when I put the dial up number in the settings to stop all applications, the i-opener wouldn't restart. It would stick at the i-opener startup screen no matter what. Pressing CTRL-ALT-DEL on a regular keyboard made the dialing light turn solid and then the system turns off.
I pressed power to turn it on. As soon as the dialing light started blinking, I pressed power again to turn it off. Then turn it on again. Then, the system came back to life! I immediately changed the dial-up number to 00000 and pressed Enter to save it.
I also found out some info, which I don't know if it's new. It's about where things are in the i-opener's interface. This stuff is weird. I found it out by printing some pages out (with the Print button on the keyboard) in the config pages, etc. I have a Cannon BJC-2110 printer.

It just leads me to think that the entire OS is the web browser (running on top of QNX, of course.)
