flexfax: DTE to DCE data underflow

[Daniel Jung <Daniel.Jung@megabit.net>]

Hi,

I'm using an ELSA Microlink 56k Modem to send and receive faxes.
Really most faxing actions do very well, but unfortunately some
fax-devices can't receive multiple-page-faxes.
The error-messages looks like the following.
Is there a way to resolve my problem?

Yours Daniel
