I spent 2 days with this. I use a T.38 termination service (t38faxing.com) that works fine, but my t38modem just sends at 1440 bpps. hylafax tries to sync at 4800 and then fallsdown to 2400 bpps.
t38modem’s log gives me this:

Thanks a lot you are really helping me.
I’m composing a new article that fixes some issues in where you have mistakes.

    • priority: 5 --> 7
     
  • The T38Modem Version 1.0.0 is too old to help you.
    Try T38Modem from CVS trunk.
