NCSA Telnet Digest July 14, 1989 Volume 3 : Issue 01
--------------------------------------------------------------------
Subjects:
Macintosh telnet 2.3 is here!
tn3270 memory partitions
2.3b8 cures conflict with MSWord
3C503 problem with test application

See our anonymous FTP server for version 2.3 of NCSA Telnet
for the Macintosh. An official announcement will go out next
week and include more information on how to get it via email.
Please do not send me a request to get the software via email
or BITNET. I will provide details in an announcement next week.

Subject: tn3270 memory allocation suggestion
In V2.29 of the Telnet Digest, Peter DiCamillo discussed how to get around
a problem with tn3270 on a Mac II (or other large-screen Mac) by increasing
its memory partition size under MultiFinder.
In my view, messing around with memory partitions is a nuisance, completely
contrary to the plug-in-and-go philosophy of the Macintosh. Might I suggest
another solution to the authors of tn3270: allocate the off-screen bitmap
in the system heap.
Under MultiFinder, the size of the application heap is fixed when the
application is launched, but the system heap is free to grow. Therefore,
it makes sense to put large, unpredictably-sized objects there, *provided*
you remember to free them before the program quits.
The advantage with doing this over using the special MultiFinder
memory-allocation calls are:
* you can hang on to the memory for as long as you need it.
(Apple doesn't recommend you allocate MultiFinder temporary
memory across calls to GetNextEvent).
* you can allocate pointers as well as handles.
* you can use virtually all the normal memory-management calls,
such as HUnlock, HLock, and SetHandleSize. In particular, you
don't have to remember which heap you got the block from
when you come to free it.
If you're not running under MultiFinder, of course, you should put
everything in the application heap as usual.
So how do you tell if MultiFinder is present? An article in MacTutor
a few months ago gave an ingenious way of doing this: simply check if
the application heap is adjacent to the system heap. In MPW C, the
code looks like this:
MultiFinderPresent =
(THz)((LongInt)SystemZone()->bkLim + *(LongInt*)SystemZone()->bkLim)
!=
ApplicZone;
I have used this technique myself in an experimental picture-viewing
application. It will successfully load in and display 24-bit RGB pictures
nearly a megabyte in size, while running in a MultiFinder partition of
just 384K.

Subject: Telnet/MSWord problem is history!
I have now upgraded my Telnet to v.2.3b8 and now all my troubles have gone!
But I believe that the problem existed also in version 2.2....

Subject: NCSA TELNET PC 3C503
Dear sirs:
I must be doing something wrong; when I try to run the TELBIN.EXE
from 3C503.tar in /contributions, I get blinking blocks of colored punctuation
marks on a hung PC.
I did anonymous ftp from zaphod on 5-July about 16:00 MDT to our
Pyramid "4.2+BSD", with ftp>type binary. Then tar -xvf got me ftpbin.exe
and telbin.exe. Then downloaded to my PC (Zenith 158 -- XT clone) with KERMIT,
producing telbin.exe of 229872 bytes in MS-DOS. It's not usable somehow.
Even SYMDEB dies trying to look at this file; it is obviously not a well .EXE.
Any clues appreciated; this new 3C503 under my hood is not impressing
the girls on my block if I can't do anything but rev its diagnostics in the
driveway. Thanks.

[was KERMIT doing a binary transfer also?

Subject: TELNET for 3com503 board
I received a copy of this through Tim Krauskopf and have been playing with
it over the last week. The program seems to be giving me some errors that
I have been unable to resolve. I work with AT&T, and therefore we use a
number of different AT&T computers. I have been experience a problem where
the 8086 based (6300, 6300wgs) and 80286 based (6300 plus, 6312, 6310)
PC's are crashing with a message "parity error on system board" shortly
after terminating my telnet session. I have tried all combinations of
io address and address. I've disabled all other TSR software on the machines
to make the environment as vanilla as possible. The machines are all running
DOS 3.2 Rel 2.02. The easiest way to duplicate the problem is to connect to
some Unix machine via telnet, terminate the session normally, then run some
application that is memory intensive (Windows is a good one) and generally
within a minute it will crash. On the 6300 plus, all you have to do is
type at the keyboard for about 15 seconds (just cd or dir a few times).
Any ideas as to where this is coming from???

Subject: UB PS-NIU & You
Help! Is there any plan to make NCSA Telnet work with the Ungerman-
Bass PS-NIU network cards for the IBM-PS2 machines. I sure would like
to get a copy of this as soon as it's available (or as soon as I can
find out where to get it via ftp).
Thanks,
Terry

There is no packet driver for the BICC Data Networks ISOLAN, nor is anyone
working on one, to my knowledge.
I now have a packet driver for it. It will be in the next release.
