I just installed Hylafax with Iaxmodem and I am not getting good results when receiving faxes. I can see that the modem is reporting the following: Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 2400 bit/s Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 4800 bit/s Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 7200 bit/s Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 9600 bit/s Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 12000 bit/s Mar 31 16:19:08 pbxoficina FaxGetty[5377]: MODEM Supports 14400 bit/s Is there a way to limit the speed of Hylafax to 7200 bits/s to get more reliable results? -- Carlos Chavez Prats Director de Tecnolog?a Telecomunicaciones Abiertas de M?xico S.A. de C.V.

I Guess you can edit the following line in your hylafax config file for your iaxmodems. Class1RMQueryCmd: "!24,48,72,96" Put exclamation in front of 96 (as it is done with 24) and it should disable the receive with that speed.> > Is there a way to limit the speed of Hylafax to 7200 bits/s toget> more > reliable results?

You can disable any particular speeds with the Class1RMQueryCmd and Class1TMQueryCmd options: Class1RMQueryCmd: "!24,48,72,96" Class1TMQueryCmd: "!24,48,72,96" Will disable V.17 in sending and receiving. My iaxmodem config file for HylaFAX suggests using this Class1RMQueryCmd option but not the Class1TMQueryCmd (so V.17 works in sending but not receiving). That said, eliminating any speed may not get you any more "reliable" results. If you're having problems post the HylaFAX session logs here, and we'll try to go from there. Lee.
