Early on in grad school, when I had to travel, I would borrow a portable device -- the first one was a Radio Shack TRS-80 Model 100, which had a built-in 300 baud modem. When we bought the last of the IBM Personal Computers (4.77 MHz, 640KB memory), we got a 1200 baud modem. But two years later, Mrs. Dr. Phil was doing dial-up to an IBM mainframe using a 3270 terminal emulator, so we bought a 2400 baud modem. When we got the 166 MHz Micron PC, we bought a 28.8 KB modem, half the price of the 56K modems which were just coming out.

Now we're all WiFi, DSL, MiFi and T1 at home & work, and never get to hear the modems sing.

Hardly feels like working. How do you know if you're connected? (grin)
