As noted above, there's more to working with a modem (or any serial device) than just opening it. You have to deal with issues like buffering, inter-character delays, baud rate, parity, and reading and writing from the same device. Rather than reinvent the wheel, I'd suggest using something like minicom or kermit. If you have to write a script or you're just interested in learning about it, you should read Chapter 11 of "Advanced Programming in the UNIX Environment" by Richard Stevens. -- tim writer <tim-s/rLXaiAEBtBDgjK7y7TUQ at public.gmane.org> starnix inc. tollfree: 1-87-pro-linux thornhill, ontario, canada http://www.starnix.com professional linux services & products -- The Toronto Linux Users Group.

SCO is pretty much a starving, almost-dead, shrivelled, emaciated near-corpse and for all that, is making quite a racket. They haven't been able to ship a compelling product in years. Any time I've ever had to support SCO Unix I've hated it. ALL of the other UNIXes are much more amenable to easy administration, and a lot more of the usual tools you'd expect are there. Anyway, what happens if SCO folds up and goes out of business? How bad would it be if Microsoft bought the leftovers of SCO and decided to continue the fight, just for fun? Could Microsoft afford to litigate Linux into oblivion? At least in the US anyway? Finally, would it be possible to get concerned Linux users together to buy SCO? Or at least to buy the scraps if they folded up? Maybe then we could officially bequeath UNIX to the public domain... If each angry concerned Linux user out there put $100 into this cause, could we do it? Dave... -- The Toronto Linux Users Group.

Good news: blender is now free

The blender 1.5 manual is dated October 1998. The program could be downloaded with most features available. Through a small fee you were able to get a key file to unlock some additional features. The program went open source July 12 of last year. For more details (and a one year report on the program's development since it became OS), take a look at: http://www.blender.org/modules.php?op=modload&name=News&file=article&sid=62… (The above URL should be all on one line with no spaces.) -- The Toronto Linux Users Group.

Well you could install the cupsys printer system (much much better than lpr/lpd) and the approrpaite cupsomatic/foomatic packages to get http://localhost:631 working and see if using the web interface it works then. It has a pretty good list of printers and ports to choose from. Assuming the cable is right, that should do something. Well hopefully. Lennart Sorensen -- The Toronto Linux Users Group.

sign your name to support the Canadian SCO response
by btraynor-zC6tqtfhjqE＠public.gmane.org 25 Aug '03

25 Aug '03

If you would like to publicly support the work of the Canadian Linux Interests Coalition (CLIC) in organizing a Canadian response to SCO's attacks, you can now do so -- visit http://www.linux.ca/clic/endorse.shtml to learn how. Three ocluggers have already stepped forward, and the more endorsements CLIC has--from across Canada--the better we can show a united oppostion to SCO. Thanks Bill -- The Toronto Linux Users Group.

If these guys keep working on You don't really need to buy the docs to get started. There are plenty of tutorials on the web. If you still like it afterwards, buy the docs ;-) I agree that the learning curve is very steep. I used Blender before (came with better Linux distros as payware demo since 1999 or before). I am very impressed by the speed even on substandard hardware and by the *size*. This is a 3d animation studio with game scripting capability that weighs in under 3Megs !!! Microsloth has a lot to learn about getting animations right and code small (and fast!). Peter -- The Toronto Linux Users Group.
