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

Title: RE: [hylafax-users] T.30 T2 timeout, expected page not received

I'm running RedHat 9.0, with Hylafax 4.1.7, and three internal USR modems(older ones, not sure of the model at this moment) for incoming only.  On two of the modems, I get about 5% failure rate with the explanation "T.30 T2". On the other the rate is around %15.  So I'm going to switch that line to another RedHat9.0 box that will run Hylafax 4.1.8, and use an external ZyXel U-1496 modem. 

I'll try and remember to send an update this list...

Thx,
Kevin.

This is probably a USR-specific shortcoming, but it could be due to
line problems or other issues, so switching modems to something non-USR
will probably help, but it may not.

There's really nothing HylaFAX can do here to improve the result.  The
modem reports (erroniously) the end-of-page signal (DLE+ETX, NO
CARRIER).

It is a good modem.
