- Interesting. That's what USR told me, too.

- I'm not holding my breath.)

- The modem never made a call.
-
- The way I read the (too terse) documentation is that &N sets the rate
- you want to connect at, and will "NO CARRIER" if that rate is not
- achieved *UNLESS* you also use &U to set the minimum desired connect
- speed.
-
- As far as I can tell, the modem will disconnect if the &N speed is not
- achieved regardless of the &U setting. "GSTN Cleardown" is cited
- as the failure reason.
-
- Setting &N to anything but 0 results in the "Fallback Enabled" status
- in ATI6.
-
- USR Sportster 28,800 modems are junk. No ifs, ands, or buts. (Not for
- this reason alone. This one's just easy to demonstrate.)
