I have problem with Zyxel U90E modem when running Hylafax. When the baud rate for sending side fax machine is larger than 28000 bauds, the hylafax will not handshake and will have the following hylafax logs:

Feb 15 16:38:44.78: [ 8358]: <-- [4:ATA\r]
Feb 15 16:39:45.40: [ 8358]: --> [10:NO CARRIER]
Feb 15 16:39:45.40: [ 8358]: ANSWER: Ring detected without successful handshake
Feb 15 16:39:45.40: [ 8358]: SESSION END

In other words, a V.34 sender will not be able to send to the Zyxel U90E. This is not surprising. The ANSam signal seems to be throwing things awry.


Both class 1 and 2 configuration not work. I have already put the line "ModemRate: 19200" but it still not responding until I manually change the baud rate of sending side fax machine to a lower baud rate.
How can I force hylafax negotiate with sending fax machine at a lower baud rate.

You can force negotiation at a lower rate, but you can't force the sender to not try to use V.34. I don't know how you could resolve the matter other than changing modems or preventing all of the people that send to you from using V.34.


I don't know if Zyxel supports their analog modems any more, but if they do, and if they will produce a firmware fix for you, then that's another option, I guess.
