Re: [hylafax-users] failure to receive silence

["Andrew Rinaldi" <andrew.rinaldi@xxxxxxxxxxxx>]

Hi Yannis,

You really need to define your requirements in terms of reliability and
compatibility.  If this is in important installation then the simple answer
to your question is no.  If you want a more complex answer then take a look
at hylafax.org or the Microsoft SBS archives and search for USR and
Smartlink.

As a minimum requirement you should really look for a modem fitted with a
Agere Venus chipset.... some PCI cards still exist with this chipset.
However, given this is over 10 years old, at the end of it's life, and not
RoHS compliant (I'm guessing you're in Europe and care about such things)
then you may want something that's brand new and supportable....

Subject: Re: [hylafax-users] failure to receive silence



This is a hardware fax modem, and I'm not sure we could justify the cost.
Aren't there any internal PCI softmodems that work well with linux+hylafax?
Any suggestions for good software-based fax modems (preferrably pci,
otherwise external) would be much appreciated.

Thanks
Yannis

	You will have very limited success with the Smart Link modems when
used for

fax

products;

	Lukasz, Lee, thanks for the suggestions. I tried it out and now I'm
getting
	a "No receiver protocol (T.30 T1 timeout)" error (see log below). I
also
	tried sending the fax using an external Smart Link USB modem (driver
slusb)
	and the fax went through without problems. So the error I'm getting
has to
	do with the internal PCI modem. Is there any other configuration
option I
	could try?
	
	We'd much rather use an internal PCI modem than an external one, are
there
	any suggestions? Which internal PCI modems are known to work well
with
	hylafax for production environments? Since we will need to order
large
	quantities, the lower the price the better.
	
	Here is the new log:
