<h1>Motivation</h1>
|
|
|
|
<p>The different project team members initially had somewhat different motivation,
|
|
and probably still have. But the following points probably covers most of them:
|
|
|
|
<ul>
|
|
|
|
<li>Educational. There is very little DSP-software freely available for use on
|
|
standard computers. A working fax-machine designed purly as free software could be
|
|
a great aid to future signal processing professionals (Project team members
|
|
included!).</li>
|
|
|
|
<li>Practical. With ISDN installed at home, at least in Norway, you need
|
|
to buy a separate adapter or an expensive phone with analog phone-line sockets
|
|
in order to be able to use a standard fax-machine or fax-modem. A much simpler
|
|
and less expensive setup would be possible if Linux could send and receive faxes
|
|
over the ISDN-line directly.</li>
|
|
|
|
<li>Challenge 1. Users of MS Windows can send and receive faxes using
|
|
inexpensive ISDN-cards, and it is about time Linux catches up in this
|
|
arena!</li>
|
|
|
|
<li>Challenge 2. The fact that a fax-modem needs some timing-critical
|
|
code to work is a challenge to the Linux operating-system as such. In the
|
|
Windows world, the fax-modems seems to be implemented as relatively low-level
|
|
drivers with lots of backing resources. It is a challenge to implement the
|
|
same functinality in a user-program on Linux, as the kernel is quite large
|
|
enough already, thank you! (Except for flexible logical volume management
|
|
and virtualized and safe graphics card drivers which I'd
|
|
like to see in the kernel...)</li>
