Subject: minor cosmetic bug

One thing I have noticed about all the NCSA telnet versions I have used.
If you have a selected area on the screen (like to do a Print Selection)
and let it scroll off the top of the screen without un-selecting it,
some time in the future a selected area of the same "shape" appears in
the display.  Since it is usually a long time in the future, I suspect
some kind of wraparound, perhaps a 16-bit wraparound in the selected
screen area cells.  This might not be enough of a problem to even diagnose,
much less fix...

I too have had problems with Telnet and Word 4.0.  When running 2.3b versions,
and word, I have had word crash on me outright, and have telnet tell me that
it was out of memory for a new session (even though I only had 2 open and had
room for four or more).

Machine: Mac SE 2.5 Megs 6.0.2 system.

You asked for some typical problems with the NCSA terminal emulator.
The following are tested against 2.2 on the PC; your mileage may vary.
In general, I think that there are LOTS of little bugs in the terminal
emulator; when you fix these I'll report more.  Most, as I've remarked,
are not serious.

For a more accurate emulator, see my version of the VTEM package
recently posted as part of tooltool, or available for anonymous ftp
from hogg.cc.uoregon.edu as pub/vtem.shar.

Some typical bugs:

0/ embedded control characters in an escape sequence terminate the
   sequence instead of having an immediate effect.  For example,
   ^[[10;^M20r should execute first the CR then the SET SCROLLING
   REGION.  See the VT102 manual, page 63.
1/ autowrap mode is broken.  If you receive ^[?7h^[[10;80fx^[[Ay you should
   display a y in column 80 with an x under it in column 80.  Instead,
   you display x in column 80 and y in column 1.  This is perhaps the
   most serious bug I've seen, and the one most likely to break display
   programs.  In general, a character printed in col 80 sets a flag that
   says the NEXT character should be preceded by a wrap.  However, any
   cursor motion clears the flag.  Your implementation is to perform the
   wrap immediately, which is wrong.
2/ Lots of bugs with scrolling regions which may also break some programs.
   ^[[23;24r (2 line scrolling region at bottom) creates a 3-line
     scrolling region.
   ^[[5r should set the scrolling region to [5;24].  Instead, in NCSA
     Telnet it sets it to [4;24] and seems to get the emulator totally
     confused.  My description of the behavior is not complete, but it
     is buggy in any case.
   ^[20;20r is illegal since TOP isn't less than BOTTOM.  However, on a
     real VT102, it is ignored, while in NCSA Telnet it sets the scrolling
     region to [1,20] or somesuch.
3/ origin mode doesn't work at all.  ^[[?6h seems to be a noop.
4/ RESTORE CURSOR i.e. ^[8 if no previous ^[7 has occured should home
   the cursor (and on most versions of the VT102 ROM restores character
   sets and attributes to a reasonable value).  In NCSA it restores things
   to a random state, including a random cursor position.

Subject: request drop ftp -n option if passwords enabled

Just enabled password protection on ftp and noticed that the network menu
command "send ftp command" still puts the -n option on the generated ftp
command.  It is not useful to bypass ftp signon if ftp signon will later
be required to transfer files.

If it knows (or can be made to know) that password checking is enabled,
perhaps it would be a good idea to supress the -n option, so it just
generates:

    ftp 123.45.67.89

The next step in the password stuff would be to distinguish between reading
and writing.  I think I would set my machine up so anybody could read the
disk but only I could write it...

how can i get a version I can use on my pc? I have no unix system available
and do not know how to get TAR or UNSQUEEZE or the like.

thanks!


[We generally assume you want to connect your PC to a unix system when
you get NCSA Telnet.  So we assume tar.  But we do have a least common
denominator -- you can get a disk and manual from us for the cost of
disk and handling.  It takes a while, but you don't need tar.
We have a catalog we send out, request by USnail:

I have seen a lot of postings mentioning a version number of
NCSA_Telnet, without explicitly mentioning what machine they are for.  I
believe most of the recent postings have been about the Mac, but that is
just guesswork.  I would appreciate it if references to version numbers
would include the machine for which that version is implemented.  Thank
you,  -David-

Patrick, I appreciate your efforts to make a TSR version of NCSA_Telnet, and
I may find it useful under certain cirsumstances.  But PLEASE, make it a
command-line option so that I can still use it like I do now.  I often
have memory constraints, and one of the redeeming features of
NCSA_Telnet is the fact that it is completely unloaded when exited.

The way it is set up now it runs as an application unless you opt to
Terminate and stay resident.  Unfortunately, I have ended my work on
TSR Telnet as I graduated and no longer work for the NMSU Computer
Center.  As far as I know the work on it is suspended currently.
If you want the source or any other info on the project mail to
Dave Rocks ([e-mail])

Thanks for your interest,

[Seems to me that David didn't remember to include which version of NCSA
Telnet he was referring to, but we will assume, as Patrick Gaughan did,
that he was referring to the PC version of NCSA Telnet.  Tim K]

tn3270 works fine under MultiFinder.  However, as distributed, tn3270
does not have its memory size set large enough for a Mac II.  This is
because tn3270 requires memory for offscreen bitmaps, and the size of
the bitmaps varies depending on the screen size and number of colors.
In my experience, any problems running tn3270 under MultiFinder have
resulted from the memory size being too small.

To adjust the memory size, use "Get Info" from the "File" menu in
Finder or MultiFinder.  Set the Application Memory Size to a large
number, for example 700K.  Start tn3270, and select "About tn3270"
under the apple menu.  Then click on the "Storage Info." button.  The
dialog box which comes up will indicate how much storage is in use by
bitmaps, and how much is available.  The Application Memory Size should
be adjusted so that the amount of available storage is at least 64K.
The graphics bitmap will not be allocated when there is not enough
memory for it, so the memory allocation can be reduced by the size of
the graphics bitmap if it has been allocated, and you are certain you
will not be using 3179 graphics during your terminal session.
