Problem with Siemens C35 + Psion Revo + Easyfax

Thomas,

<< Sorry, if you did not understand me correctly, but I already fail in
SENDING a fax
That's, indeed, possible. The fax protocol is an old one, predating the
use of mobile phones by quite a number of years. It has a few timing
constraints a mobile phone connection isn't always able to meet.
Siemens' implementation of a Fax Class 1 computer interface doesn't
help in this respect.

Another aspect is that fax machines, fax-modems and mobile phones don't
always operate that well with each other. There are combinations which
prove to be more troublesome than others. One of the fax machines at
our offices is rather selective, for example. Using my Nokia 8810 there'
s a chance of one in four of the fax getting through. While there's no
problem in using a Psion Dacom V.34 Gold Card Global.

<< I do know that my C35 only supports Fax Class 1. But as Easyfax
supports Class1, too, it should work with the right init string
I'm afraid that's not the case. To cut a long story short, with Fax
Class1 there's a higher chance that repeated time-outs occur between
C35 and remote fax device. Resulting in the call being dropped when the
maximum number of time-outs has been exceeded.

Yes, it is.

Thank you very much for your detailled explanations, Kevin.
Yes, I have just tried sending a fax to our office, because there is a
"fax only" machine. But, no success. The same error message appeared
at the same time. :-((
What now?? Any idea?

Many regards from Germany,

Thomas,

I had the same problem trying to send faxes from my Series 5mx + Nokia
6210 to fax machines at offices in work. Is the machine you are sending
to, one of those combination machines - fax, phone and answerphone, all
in one unit?

Nearly all of the machines in my workplace are, and most are left in
"auto" mode to detect who/what is calling. When a call is made, if this
type of machine doesn't hear a fax "ready to send" tone being sent, it
will switch to the phone/amswerphone after about 5 seconds. I have to
make sure someone at the receiving end, manually sets the machine to
"fax only" so I can send a fax to it!

As the 6210 modem doesn't appear to send the "ready to send" fax tone
(it waits for the equivalent "ready to receive" tone from the _other_
machine), sending _always_ fails, with the 5mx fax program just "timing
out". The fax machine in my office is just a fax machine, so will send
the "ready to recive" tone when you ring it, and the 6210 starts
sending.

Have you got a "fax only" machine you could try sending to?

Just a thought?

Cheers,
Kevin.

Mike, thank you very much for your answer!
Sorry, if you did not understand me correctly, but I already fail in
SENDING a fax. Yes, I have tried the AT&F string, but the problem kept
the same: the receiving fax machine on my desk answers the call, I can
see the fax identity of Easyfax in its display, my C35 reads FAX on
its display, the machines both try to connect baut fail with the error
message above.
I do know that my C35 only supports Fax Class 1. But as Easyfax
supports Class1, too, it should work with the right init string.
Unfortunately the modem commands by SIEMENS (*.PDF) do not say
anything about fax.
Please, could you give me more hints??

Please see my email.

Many regards,
Thomas

...

The C35 phone only supports Fax Class 1 which is not ideally suited to use
over GSM networks. I have normally managed to send faxes with my S35i but
receiving them is extremely unreliable. I don't know what intialisation
options are in Easyfax but the usual setings for Siemens phones are a reset
string of "AT&F" with the fax string left blank.

Do you have the URL to download Easyfax as I have been unable to find it in
the downloads for either S5 or Revo on Psion's site? Alternatively, could
you email me a copy and I'll put it on my website. Thanks.
