[hylafax-users] Modem Wedged problems

["Mark Bennett" <Mark.Bennett@xxxxxxxxxxxxxxxxx>]

I am having fairly frequent "Wedged" problems with my modems.

My Hylafax server processes around 1500 faxes / 2500 pages a month.

The wedged issue doesn't seem to be modem brand specific, as I have
tried a number of brands including very old 14.4k models.

Currently I have 9 x Dynalink 1456VQE external, with the Topic chipset

tty config is "standard topic" settings.

When wedged, the modem shows carrier present, and seems unable to be
reset.

Also, a modem sometimes will just lock up, and not even a wedged message
is sent.
It is always the same sender when this occurs.
The sender is the biggest multipage sender, and it locks up during the
later pages.
Typical log error for a lockup is "T.30 T2 timeout, expected page not
received"




Typical session log resulting in a wedged modem is
