- I was wondering how you interpret the results of the at%q command. The
- modems I work with (Maestro 288FM's, and 144M's) just dump me a number.
-
- This number is usually in the 15 - 25 range for a 28.8k modem and in the
- 1-2 range for the 14.4k modems.
-
- I know that the at%q command gives the EQM value, but what value is bad
- and what is good. At what values would you expect errors, retrains, or
- dropouts?
-
- cheers,
