And still problems with rackmounted Zyxel.. :-(

[Mathias Koerber <mathias@staff.singnet.com.sg>]

And I still got problems.. I got a tip to change the modem
from class 2.0 to class 2, but even that didn't help.
The only dif was that in class 2 it hangs up with FHNG:20
after the AT+FDIS command instead of with FHS:20 after
the FDT command...

Now  here I have TWO session traces.

The first one is from my GOOD (standalone Zyxel 1496e on server 1)
to my faxmachine (a Nucleus) using hylafax 3.0pl1..:
