- I have this problems with the Supra as well. After some testing and help
- from Supra, I have determined the problem is with Supra's method for
- detecting BUSY signals. The method is very dependant on your local phone
- company's tones and timing. My Supra works fine at my Summer residence,
- and rarely detects correctly here at school. There's really no solution
- other than to put the modem into "dumb" mode (with the ATX command). The
- 1.2 ROMS do nothing to rectify this situation.
-
- In Supra's defense, the tones used here in Indiana are (I am told) fairly
- out-of-spec, so on a proper phone system the Supra should work okay. Other
- modem brands however (USR, PP&S) have no problems detecting BUSY here.
