Hmmm.  If it really has an endless roll, it should work.  How long is the
part that it does accept? About A4?  Maybe your modem has a problem
negotiating the proper length.

Is the data in the G3 file?  Can you send me such a G3 file?

Let's see...

A small increase is normal (DLE bytes have to be escaped, and sent as DLE
DLE, increasing the total size by about 1-2%).

Now this log file is not very helpful.  Not AT ALL.  You don't show the
original file length, and all I can see from the log is that it sent the
whole file with no problems (and the receiver acknowledged that!).

Any weird circumstances? Files on an NFS file system (cache effects) or
so?
