I can't take it any more. On SCO Xenix 2.3.3, my doscp takes SO long to copy files! Sometimes it runs out of memory! Is there an alternative method? (No, I don't have VP/ix - will anyone sell me a copy for cheap?) I have used the DOS utilities under Minix, and in many cases Minix will read and write DOS files FASTER than DOS. I would hope that there would that Xenix would be able to do so somehow. Perhaps someone has ported the Minix utilities to Xenix? If not, I may - before I go insane waiting for doscp to finish. Thanks, Dave Smith

Try mtools version 2.0.4 from cerl.cecer.army.mil [129.229.1.101] ~ftp/pub/mtools/mtools_sh.[1-4].Z I use it both on a SparcStation 1+ or 2 running SunOS 4.1 and on my Atari/ST at home running Minix 1.6.15. On the sparc its nearly twice as fast as the new dos filesystem introduced in SunOS 4.1.1, on the atari more than twice as fast as the tos command suite (which is equivalent to the dos command on Minix/PC.) Hope this helps.

The doscp program is a bit quadratic. It does seem that Unix
programs tend to be a bit quadratic dealing with floppies unless
they can be made to use a track at a time.
Now that the 286 is Dead, perhaps someone can hack soem doscp
program that buffers a track in memory, or perhaps caches the
entire floppy.
Since I have Merge and Vp/ix I don't need to do the hacking myself.

[...] Part of the problem may be that you are using /dev/install to read the floppy (which is slower because it goes about figuring the density of the diskette it is reading); using the explicit device name can speed things up a bit (but not much, mind you! :-) For example ... doscp /dev/fd096ds15:/dos/is/evil /tmp -- Michael Stefanik, MGI Inc, Los Angeles | Opinions stated are never realistic Title of the week: Systems Engineer | UUCP: ...!uunet!bria!mike ------------------------------------------------------------------------------- If MS-DOS didn't exist, who would UNIX programmers have to make fun of?

I have a program which reads and writes XENIX tar floppies on DOS. It's fairly fast. E-mail if interested. bryan@well.sf.ca.us

I would assume that doscp would not use /dev/install to get c:/dos/is/evil :-) Anyhow, it's just another one of those things that I guess I'll have to live with. Dave Smith dls@genco.bungi.com
