Hello Matthias and Mark,

I'm the author of the fax program Mark is talking about. It is called
Ecofax and it was specifically developed for blind and visually
impaired users.

That's correct. It is the "File not found" error.

Yes, that's correct. I have tested Ecofax on my OD 7.01 test PC, and here
it works without any problem.

It is possible that the directory pointed to by either TMP or TEMP (Ecofax
recognizes both) is not a valid one. In such cases you usually get a clear
error message -- not a simple runtime error message. But there was one
customer that reported a similar problem some time ago, and, as I found
out, he had a quite unusual network setup for the temporary directory.
The problem was solved by setting TEMP to point to a valid network
directory.

While I generally tend to agree with your statement, having been a
programmer for quite a lot of years now on almost everything
Intel-based from MINIX to OS/2 Warp 4, including Linux and FreeBSD, 
I know out of personal experience that you simply can't foresee each
and every situation a given program will be used in... That's why there is
a technical support. And that's also why I'm committed to improve the
program through further releases.

Ecofax is being used by quite a lot of happy blind and visually impaired
users around the world, despite the occasional installation quirks.
But the same is true for OpenDOS as well -- even if I find it a very
interesting project.
