Re: [hylafax-users] "T.30 T2 timeout, expected page not received" ERROR

[Bill Fung <bill@xxxxxxxxx>]

Dear Lee,

Thanks for your reply. Do you mean the problem is due to smartlink 
modem? Actually, I tried 2 pci modem and they don't work with hylafax (1 
cannot auto-answer receive fax, the other cannot find suitable driver).

How can I test and confirm that it is a problem of smartlink modem? Or 
can I tune the parameter to solve the problem?

Your advise is valuable. Thanks a lot.

Btw, what is TCF? the smartlink modem can receive most fax without 
problem...

Mr. Fung
