Software flow control didn't do jack. I also tried some ATI[0-7] commands, which are supposed to return a fair amount of data (and do, on the Sportster). The lights blink but I just don't get anything in the terminal.

I fear there's some kind of electrical issue. On one of the non-working modems, I'm not positive I have the right power supply. On the other - the one that actually blinks its lights - It's the original wall wart. But something may have failed internally.
