Subject: NCSA Telnet 2.1 and MultiFinder
With MultiFinder running (Sys 4.2, Finder 6.0 on a Mac II) and a Finder
window open on the desktop, if I launch Telnet 2.0 or 2.1, the "About
Telnet" dialog that appears consists of only the border, no contents.
If I click in the box (to make it go away), it appears hollow; that is,
I end up clicking on the Finder window and I'm switched to the Finder.
If I switch back to Telnet and select "About Telnet" from the Apple
menu, the dialog box is displayed normally. If I launch Telnet such that
there are no windows between the dialog box and the desktop background, then
the dialog box is displayed normally.
Are there any other problems using Telnet with MultiFinder?
As a future enhancement, I would like to see the VT100 emulation use
a larger point size in a larger window (as an option).
Thanks for a great program!

The following text comes from a suggestion list submitted by
Steve Strassmann at MIT. The responding comments are mine - Tim Krauskopf
Thanks for taking the time to observe all of our (and sometimes others')
shortcomings. At least we know you really use it . . .

We had considered this window to be of limited use. I would like to
see a full status dialog instead of just finishing off the improper use
of a full window for this type of information.

On-line documentation would be a plus. Does anyone have a package that we
could incorporate?

We hadn't planned to do it, primarily because we expect users to have
one network interface, or have telnet use one of them 100% of the time.
Why would you want to use your AppleTalk (LocalTalk) interface when you
have Ethernet? Remember, using 2.1E should not preclude using LaserWriters
which are on LocalTalk (we are testing to make sure).
Also, the coding of the lower layers would require a serious re-write to
switch back and forth. The link layers are very different.

The standard, given in RFC960, is to identify DEC VT100s as "DEC-VT100".
Since this is an explicit specification, I can recommend that you add
DEC-VT100 to your termcap. This should be easier than trying to configure
dozens of Macintoshes with another termtype.
>* In the "configure" portion of the Open Connection dialog, some

>
The documentation on the configuration file shows you how to set up options
for each type of host and for each host individually. Save Set can be
used as a manual, interactive way of saving these settings. The system
administrator should sit down and design the correct configuration file
for your site so that each user doesn't have to do it himself.
>* The "Session name" isn't the session name at all, it's the address of
>the host you want to connect to. ["Window Name" is a synonym for Session
>Name.] The prompt should therefore be something like "Host to connect

>
"Session name" is the session name. See the configuration file docs.
The session name does not have to be even remotely related to the host name
and the window name can be used to override the name bar in the window.
ACK on the caps.
>* A scroll bar on the macro definitions would be nice.
>
yes. So would a real macro/scripting facility. Would you use one if you
had it? Would you think that such a thing could be reliable?
>* Put the manual into one big file (or at least fewer, larger files).

Sounds good, especially for distribution.

I would much rather allow you to select it from the connections menu and
then present a dialog which reports status and allows you to kill or
continue. In what situations does the current method present a problem?

I expect to see a more flexible version in the future. This version was
designed to give a very accurate VT100 emulation on a "original" Mac
screen. Later versions should allow you to give up the picky VT100
details and give you more screen flexibility.
>* The Telnet Set file, which keeps all these parameters around, should

>
The configuration file already uses up the TEXT type. It is edited by
users more often. We have assumed that any user who does not simply use
"Save Set", but wants to edit the set file directly, will have a text editor
which can edit non-TEXT files. There are some commercial options.
>* It'd be neat if you could support the SUPDUP protocol, since it

>emulating.
>
We are waiting for some better-recognized standard than SUPDUP. How
about NVDET (sp?)?
>* Allow the user to initiate an FTP on the mac instead of the remote
>host. Then you could use anonymous FTP privileges on a host even without
>a real account there.
>
This is on our "wish list" for those people who have picked up the source
to work on.

>right way/wrong way would make it clear.
>
This is only a performance problem. You know it when you see it because
it is so slow. An illustration would help. Shrink a window to half its
vertical size and place it in the middle of a regular size window. Then
wait for text to scroll by in the back window.

Subject: NCSA Telnet 2.1...
Date: Thu, 17 Dec 87 10:07:35 CST
NCSA Telnet Wizards,
A few weeks ago I downloaded the telnet21.Hqx and the telnet21.Sit and
neither seem to work on my MacSE, running the MultiFinder system. When you
tell it to open a new connection, it puts up the dialog with "Configure",
"Ok", and "Cancel" on it, click "Ok", and dialog goes away. No window. The
"Windows" menu lists a grayed out "rosetta.com", and the "Close" menu item
is enabled. Selecting "Close" does something that takes a little time, and
the "Windows" list becomes empty again.
I tried this on a Plus as well, without results. I tried this on the
Universal System from Apple, without results. I didn't try it without
TOPS, though. What gives?
Software:
MultiFinder System
TOPS 2.0
