That's ok. I was trying to make this correction *and* be nice! 8)

Yada, yada, yada. I believe you are correct. I've never had a problem
though!! Hey, nothing in life is "guaranteed". Also, since we're being
picky, sendfax can handle class 2 & class 2.0, which are not the same
thing, class 2 being an industry "de facto" standard which became
widely used before the official standard, (2.0) was deployed.

Cool. Save trees! Why print to paper? Why print something in Word/Lyx
just to stick it in the fax machine and then toss the hardcopy? I've
been meaning to set up a "fax server" here where all faxes are received
via modem and then a thumbnail image is generated and emailed to certain
people (with MIME and html content) and a URL is stuck in there which
goes to the server allowing them to view the full-size image and allow
them to print, delete, or hold on to the fax. Especially since we get
a lot of "junk" faxes, this would reduce paper wastage quite a bit.
