Without X the copy succeeds. I use just the cp command to copy the file. The file systems are on separate IDE disks. The cp commands returns to the shell prompt and I have about two seconds time to type the next command, when the disk makes a normal noise (apparently flushes disk buffers from RAM to disk) and everything freezes: I can't move my mouse and keyboard is dead (Ctrl-Alt-Del does nothing, Caps Lock doesn't blink the LED). I have to press the reset button, after which the fsck starts complaining during boot-up. Any ideas? The system has been very stable all the time. I made last upgrades on July 1st this year. The machine is a no-name clone 486DX2/66 with 256 kB cache and Award BIOS. The machine was bought on June 1994. I don't have any other problems with it.

Not very sucessfully though. I seem to be able to receive data just fine, but I can not send data out. I can't figure out how to tell if data is being held due to a control signal in the wrog state. I would really prefer to force the comport to set all outgoing control sigs TRUE ...AND.. ignore all incoming ones. My tcl script just issues an open command on /dev/cua0 which seems to work. After that I use read commands to get data and puts to write. Before doing any reads or writes I use stty on /dev/cua0 for the raw mode. Issuing a flush on the file after doing a write doesn't help. Thats my story. Thanks in advance for anything. Dave dbashaw@synoptics.com ------------------------------ From: Steve Pershing Subject: Re: Priorities in 1.3.45?

All you would need to >is specifiing an API for the programs to acces the demon. This is actually the real issue... the lack of a standard printing API under Unix. It's not just Linux... it's Unix in general. Because of the lack of an API, applications have to produce output without being able to interact with a printer driver to determine the capabilities of the available printer(s). As a result the output is in some generic format that may not be a good match with the available facilities. Then you have to pass this output through another processing stage to prepare it for the actual available facilities, a process that often does not work very well or in which you lose something that you might otherwise have been able to do. POSIX is apparently trying to address this, but I haven't seen the result and I don't think any vendors have implemented this aspect of POSIX. From what I've read it's based on the MIT/Athena stuff which I took a look at once and found rather baroque. Nevertheless, since Linux is a Posix system, this should be considered. Unfortunately POSIX documents are hard to come by... -- Jurgen Botz, jbotz@mtholyoke.edu "Unix? What's that?

The application needn't be aware of what printer is being used, but just switches device context to the printer device instead of the screen. I suppose by analogy it should be possible to bastardize an X-server to produce pcl-5 or hp-gl or some other printer language from a rasterized Hi-res virtual image produced by an X-app. However it would require a lot of memory, and without some optimizations wouldn't support built-in fonts etc. Imagine, selecting an X-printserver for the HP4, or a plotter or whatever, would be nice, no ?
