==> NOTE:  please send replies to my Professor, mp@pstc.brown.edu  <==

      I am looking for software to read and write half-inch, nine-track,
IBM and ANSI labeled tapes without having to be knowledgable of the
intricacies of the dd command or, more importantly, even the character-
istics of the tape to be read.  We receive many tapes written elsewhere,
and have many users who are "non-computer-friendly" who need to read
these tapes on their own.

      The software should be able to assist the user in inspecting the
tape, read and interpret tape labels (if they exist), extract arbitrary
blocks from the tape, support fixed and variable length blocks, translate
from EBCDIC to ASCII, add newline characters and strip trailing blanks
if necessary, and create labeled tapes.  We have a tape drive which
emulates an IBM 9348 nine-track drive, attached as a SCSI device to an
IBM RS/6000 running AIX 3.2.

If anyone knows of such a program (either free from an ftp sight or
distributed by a vendor), and could offer any comments on such programs,
please send me mail.  I will summarize if there is enough interest.

Thanks!

We're (trying) using the serial port, so this must be the problem (thanks!).
It seems to be interfering with getty(1)s ability to assign /dev/tty0 too
(or we have another problem).

I simply set the serial port at 38400 using SMIT and disabled XON/XOFF
flow control in favour of RTS/CTS. The latter cannot be set from within
SMIT (why not?) and must be set with the command

stty add rts < /dev/tty?

This command does not survive a reboot, apparently IBM have supplied
a workaround to this but calling support in the UK failed to find
what thi is.

Also ensure RTS/CTS is used in the modem and that your modem cable
supports it. All this gives me a link rate of 14400, but doesn't help
with throughput. From various discussions in UUCP newsgroups it would
appear that my problem may be the limited window/segment size
in AIX uucico. To this end has anyone patched the binary with more
sensible defaults ie window size of 7 and segment size of 256, or 
better still, managed to port Taylor-uucp to this platform?

the problem is my ignorance of tty's, penable, pdisable, etc,
because my SE can come in here and make it work.

I'm looking for help in either of the following:

    as my PC with Procomm
2 - Instructional reference that will be more helpful

Thanks for the feedback, and the sanity check, John - your points are
well taken.  I can say that in some cases, capacity is more important
than performance (within reason) and that with 8 machines allocating
close to half of a gig in unused i-nodes that could otherwise be used
for datablocks, I don't like to see the unecessary waste.  If I want
to sacrifice a little performance for the capability of writing 50
more megabytes, why shouldn't I be able to?  That aside, I hadn't
really considered the performance issue and appreciate your pointing
it out to me,

Austin, 1989:
We spent days mapping out every damn bit and semantic of SYS V and BSD
line disciplines.  There were several things that did NOT map 1:1 in 
BOTH directions (don't bother asking for an example...I don't have time
to sift through 1989's mail).  Instead of doing a half-baked combined
discipline, we opted for "pure" disciplines.  About 4 weeks before we
shipped AIX 3.1, a guy from Palo Alto snuck some BSD semantics in the
posix discipline while I was letting him work on SLIP.  I think the
sentiment today is to go ahead and do our "best" BSD imitation inside of
posix.  CBREAK is broken, tandem doesn't exist...the list is long and
nobody has scheduled time to beef up posix.  Too bad.

I wonder what would happen if AIX tty changed directions and became 
based on a "real" STREAMS model but did NOT have any BSD line discipline
support.  Maybe this is what IBM's Mark Brown was hinting at (I'm not a
betting man).

Well, I thought I had better correct myself.  Right after I posted the above,
I ran a couple of jobs in the background and ran sysline and got output
indicating 3 executable processes ("3r").  However, using ps xva, I found more
than 3 jobs using comsuming considerable cpu running.  I guess, the question is
how does sysline determine executable processes.

To all that have been having problems with vi hanging on ptys:
I know a few weeks ago I recommended that apars ix24329 and ix24895
would fix this problem *completely*, only to discover that it
made the problem occur more frequently.

I have made the third (and last) part of the (now) infamous

Actually, Toronto's support centre just yesterday filed a problem report
with your offices to report that putuserattr() is sucking up page space
like crazy.  My guess is that there's a lot of space it mallocs but doesn't
free up again.  This code segment demonstrates:

#include <usersec.h>

main () {
	setuserdb(S_WRITE);
	while(1) {
		putuserattr("nobody",S_GECOS,"NOBODY",SEC_CHAR);
		putuserattr("nobody",NULL,NULL,SEC_COMMIT);
	}
}

This will kill itself after about two minutes (16Mb RAM, 32Mb page).  Toronto
people reproduced the problem and sent it down your way.  A program like the
one above should suck up very little page space when you consider what it does
but certainly less than the 22Mb of page space it is consuming.

I'm glad your offices are on Internet - maybe you could allow me to ftp
a fix as soon as you have one?  This affects about 4500 users, and we'd
like to get it working soon.

I have been able to "kill" a job and get my tape drive back (8mm) by manually
ejecting the tape.  This must send a "reset" or "disconnect" signal down the
SCSI bus that terminates whatever the tar command is waiting for.  Give it a
try.

Marc, we've got your bug submission.  Unfortunately, I'm having problems
getting the pubs folks to agree to have this document under "revision

rogue document written mostly by my Driver Team guys in the porting

I'd also like to finish writing the tty section (chapter 5) to include
line/pacing disciplines and the eventual "generic tty config method"
(when that's finally coded) as well as try to keep up with the weekly

xlC supports static constructors/destructors in a manner similar to the

processes all the .o and .a files before the link, looking for those names.
munch creates a data structure that is linked into the executable.  At startup,
the runtime startup uses that structure to invoke all the constructors.

In addition, the runtime startup code looks at all shared libraries, and 
invokes the static constructors in each library.  See the 'makeC++SharedLibrary'
section of the manual to see how to create such a library.  There is a method
to specify the 'priority' of libraries, to ensure that libraries are initialized
in the corrct order.

Currently, there is no support for running constructors/destructors from shared
libraries that are loaded at run time (as compared to libraries from the ld
step).
