Subject: DV Window size info
Date: Wed, 30 Sep 1992 06:19:07 GMT
Organization: PANIX Public Access Unix & Internet, NYC

Is there any user-level mechanism for a process running in a window to
know the current window size? 

Example:
	Running the MKS Korn shell in a DV window that has
	been resized to 16 lines x 80 cols. I want to use
	"more" or "vi" in the window. Neither program
	crashes or writes video outside the window, but each
	program is smart enough to conform it's video to a
	particular size window, IF TOLD TO DO SO. 

What I'd like would be environmental variables in each
window, set by DV, that contain the current number or rows
and columns. I could then call "more" as:
	more -n$LINES


How about it QD?

They had a special offer ending Sept. 30 that let previous owners buy
DVX for $100. I got the form at the X-Window Expo so the offer may not
have been extended to the general public but I'd be surprised if they

Subject: (another) problem deleting files/directories
Organization: Nyx, Public Access Unix @ U. of Denver Math/CS dept.

I have a problem.
I ran PC Tools Diskfix on my hard disk and it discovered some lost
clusters. I chose to save them, so I could look what was in them.
So Diskfix created 25 directories and 1 file.
The file didn't make any sense to me, so I deleted it. The
directories all contained 3-10 files of 0 bytes and most of them
had very weird names. I wanted to delete all of them but then the
problem showed up. First I tried PCTools Directory Maintenance,
which allows to delete an entire directory, regardless of its
contents...I thought. It wouldn't. It couldn't delete some of the
files in the directories. Then I tried manually in PCShell. On
most of the files I tried to delete the answer was "file not found"
although those files appeared in the file list. After a while I saw
that all those filenames were in lower case. Very strange.
Then I tried msdos (5.0) It couldn't find those files either, but
that was because most of them were hidden. So then I reset all
file attributes (with PCShell) and deleted them (with msdos;
PCShell still couldn't find them). Then I tried again to remove
the directories, which should be empty now...Well some of them
were and disappeared, but others still weren't empty, although
PCShell didn't show any files in them. The 'dir' command with
switches /ah did show some really weird file names, containing
[, {, `, ^, |, etc. When I tried to reset the 'hidden' attribute
I got a syntax error..maybe because file names should't contain
those characters?
 
Does anybody know how to get rid of those files?

This is a common misconception, that the modem should talk at the same
rate as the carrier sent by the modem.  It is true that modems which use
2400 baud or slower will require these rates to be equal, but generally
the faster modems will let you talk at 1200 baud to the modem while they
talk at 9600 baud to the other modem.  This is a silly thing to do, but
the modem will let you.

What you should always do with a high-speed modem is set the data rate
to the modem to its fastest speed (19200 or 38400 are commonly used) and
then let the modem talk to the other modem at whatever speed it desires.

There has been a rename directory system call for a long time (since
DOS 2?). I have a copy of a shareware command called rendir which does
just what you want, without messing with horrors like dosshell or
windows. I'm sure it must be around on the big servers somewhere.

well, that describes just about every half-decent comm package for
dos....  these days, any comm package that can't handle speeds >> 19.2,
with full 16550AFN support, is dead.

but, if you're looking for a *GOOD* comm package, here are some
suggestions:

   1) TRY THE FOLLOWING:

      *) Qmodem --- the best, IMHO

      *) Telix --- also very good, but Qmodem's interrupt routines seem
         more solid (better support for very high speeds)

      *) there are others that I'm told are also very good, but these
         two are all I've seriously tried.

      *) I also might be coding my own soon (w/ support for multiple
         active comm ports, and a different full-screen window for
         each), but since that's still in the idea stage, it might be a
         while.  :-)

there are also some things you should avoid like the plague.....

first, there's crosstalk --- absolutely horrible user interface, can't
handle high speeds at all (they even admit this), pain in the *ss to use
(oh, I said that, didn't I?), and so on.  don't even bother with this
one...it'll only cause you lots of headaches.

also, every windoze-based comm package, as far as I know, also fits
this category.  back when I was trying out windoze (for all of about
a day and a half), I tried out several different comm packages I'd
gotten from SIMTEL20.  to put it simply, none of them worked worth a
d*mn.  if you try to do a file transfer, there's some kind of delay
that seems to be built into all of them, and by the time you start
Zmodem (et al), the other end has aborted.  they also seem to lack a
tremendous number of configuration options when compared to Qmodem
or Telix.  they didn't even last as long on my hard disk as windoze
did...and it only lasted just over a day....so avoid these, too....

hope this helps.

I have a 80M harddisk, partitioned to 20M (C: boot) and 60M (D: SuperStor).
Just a couple of days ago, I install Monkey2 to D:. During the
intallation, the SuperStor drive ran out of disk space. I notice
that the harddisk LED wastnt lighted up halfway during the
installaion. Anyway, when I "dir d:", I saw all the files being
"installed". However half of them were 0 size. Hence in my case,
it only create 0 size files when it is full. I dont have any
problem of corrupted FAT etc.

Oh, I reinstalled Monkey2. I deleted more files for it. BTW,
Monkey2 installation program gave "Installation completed" even
though the files are 0 size.

Organization: The Ohio State University
Date: Mon, 5 Oct 1992 13:39:23 GMT

Thanks to the many people who responded to my question about an
unremoveable directory.  The responses were basically of two kinds,
illustrated below.  Unfortunately neither is the answer.  There
are no SUBSTed drives in my environment that I can detect, nor
are there any files of any kind in the unerasable directories.
BTW I have tried the 4dos   DEL [direc name] /sxzy command as well
as the RD command, and also executed DEL *.* /sxzy from within the
unerasable directory.  The results are that I get the messages that
there are no files matching *.*. and 'access denied' when I try to
remove the subdirectory.

What is best way to look for SUBST drives?  I've examined the 
environment and made sure ther aren't any SUBST commands in config.sys
or autoexec.bat.

Any other ideas?

Is there another driver that is compatible with the P/20  (Epson, Star ?)

Great.  Taking into consideration that 75% of MS-DOS users DO NOT
care for DOS Shell..  very impressive.  The funny thing about
MS-DOS ever since 3.3 has been the total lack of perfected
utilities.  DIR's new switches in 5.0 are great but it still 
doesn't give you that "thoroughly researched and fixed 12-year old
OS" feel.   To me it looks like Microsoft made 4.0 only
to support larger fixed disks... 5.0 to place DOS in high memory,
6.0 to cash in on the utilities market (hey, if all 60+ million
users upgrade... what a wonderful day).. only "7.0" seems to
bring anything truly new to the market... (i.e. something that
is not a response to competitors or OEM customers...).  If
Microsoft would not have had DR eating a healthy 5-10% of their
business and Compaq had not made Compaq DOS 3.31 we still may be
stuck with DOS 3.3!!! DOS 6.0 is pure money grabbing (altho
users are going to _love_ it.) Can't wait to see DOS 7.0 or
what ever it's going to be called.

I use a shell called QFILER that makes it easy to see attributes and
create or remove directories.  It doesn't do any better than the
4dos or command.com RD command, probably because they all do their
thing by calling the same DOS interrupt.  The problem doesn't seem to be
files or attributes present that I can't see.

It is my understanding that on PC floppy disks (specifically 1.44MB) that after
issuing the dos format command the layout is the following.

Track 0 : Boot Record, File Allocation Table, Root Directory
Track 1-79 : Data Storage

Questions :
Is this correct ?
How big are each of the entries in track 0 for a 1.44 MB diskette ?

Thanks very much 
Scott
