- I am using a sporster 33.6 on a mac, and have noticed much of the same
- (except case number 4.)
-
- My modem consistently drops carier, drops carier immediately after
- connect, fails to answer, etc.
-
-
- When in fax reception mode, what is a good init string to use? I have
- finally got it to auto answer, but the modem doesn't send out the fax
- signals, and only starts emiting these signals if it detects a CNG tone
- from the fax machine immediately after connect with the fax machine.
-
- As a matter of fact, my modem just dropped carrier, I had to reconnect.
-
- The modem frequently connencts at 21600, and sometimes even at 14400. I
- have only once connected at 28800.
-
- As far as the drop carrier is concerned, I have tried to increase the time
- the modem waits after loss of carrier to drop the carrier to 254
- miliseconds, i.e. S10=254, and it still drops carrier.
-
- Can any one suggest some good init strings that will resolve these problems?
-

- Thanks
