Hello!

This is a part of my logfile:

During the transfer of the file /var/spool/fido/outbound/00f103e8.out
the ISDN-Connection breaks off. But if I send the file with a simple
Modem, the transfer goes without difficulties:

Apr 29 19:14:23 arktur ifcico[1218]: options: Call Hold PUA WaZOO EMSI

....... and so on ........

What's the cause for the breaking off of the file transfer via ISDN?

Greetings
Wolfgang
