The cupsd demon has a built-in web server. I found cups to be the easiest to use and it supports my HP Deskjet 660C perfectly on a PC with the default hpijs driver. Plus you can configure it with KDE's control center or GNOME's print manager. --- Anton -- The Toronto Linux Users Group.

I prefer to get into the stuff I know, albeit poorly. I think the concept of web interface is good, but it requires httpd to work and adds another level of indirection. This is fine if you want/like a m$-type interface, but not if you want to get under the hood. Why replicate m$ behaviour? When you get down to it, IMHO, "cat" is the way to go. lpd is second best (1 level of indirection). cupsys is third (multiple levels of indirection; httpd required). (Yes, I know that if you extend my logic, I'd be talking to the printer in hex.) Is cupsys an interface to /etc/printcap? The cable works all right. -- The Toronto Linux Users Group.

It seems like they have excluded the lynx user... Using Technology to Promote Social Inclusion Information and Communication Technologies (ICT) are increasingly becoming a basic need for people living and working in Canada. In order to have control over one's life people need to access and be able to apply the standard tools of our society. Not being able to access or manipulate ICT creates a disadvantage to those without access or skills. The St. Christopher House Community Learning Network is about enhancing people's ability to use computers and the Internet to engage in meaningful social activities. -- The Toronto Linux Users Group.

I "set line /dev/ttyS1", connected and nothing came out. I returned to the kermit prompt and "set speed 9600" (it defaulted to 38400). That worked. Now all I need is an /etc/printcap entry and I'm done. Unfortunately, I don't know the printcap syntax well. I guess I'll have to learn. -- The Toronto Linux Users Group.

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.

Is it at this point that M$ buys the ...what? ...copyrights? >...SCO? outright for nothing in a short stock trade? Remember this? > > NOW it's getting interesting! This might be very very important. 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.
