flexfax: Send failed: No answer from remote

["Hans Feringa (HFX)" <hfx@shelob.demon.nl>]

Hi,

I have a problem with sending faxes. I can receive faxes ok.

I have a E-Tech Fax modem E56K RVP (class 1).
I tried the e-tech config example, but that did not work for me.

The problem is the following:
1) the modem is initialized
2) then starts dialing
3) other end picks up, and tries to do the handshake
4) no response from my end
5) eventually other end gives up
6) I find in my logs "No answer from remote"

I have no idea where to start looking.
Session tracing is 0x4F, Server tracing=0x16f
Can I get some more/other information about the handshaking
process in specifying other values for either
session tracing or server tracing?

I assume it has something to do with how the modem is
initialized, but I do not have a clue what is causing
this.

Your responses will be appreciated.

Below are:
1) part of the config.modem file
2) log taken from syslog (removed some of the interpretation
   that is already present in the "raw" answers from the modem)
3) session log

Thanx,

Hans Feringa
