- Subject: tabs and fonts
-
- It turns out that tabs should be nondestructive... The problem I was
- seeing was due to another problem where <ESC>[2K would not correctly
- erase to the end of line.
-
- On another note, I've noticed that zero and uppercase "o" and
- lowercase "l" and uppercase "i" are exactly the same... While I
- realize that this is an attribute of the font being used (Monaco), I
- was wondering if there was a better fix than:
- (a) modify it in your system
- (b) include a modified copy of Monaco in Telnet...
-
- I would fix it as:
- make upper case "i" have "serifs" or danglers on the top and bottom
- put a dot in the middle of zero - except in bold face zero
- which needs more - put dots on the upper right and lower
- left as well as in the middle to make it look like it has
- a slash through it...

- I know sources have only been out for a short while, but has
- anyone started work on a tn3270 application based on ncsa telnet?

- I know that you will want to know the version of NCSA telnet: I don't
- have it because the Mac I was using has been taken away to replace the
- Kinetics board (monitoring with an Excelan Lanalyzer showed it could
- not send out packets at a high rate without crc errors, short packets etc.).
- However, I believe the questions are relevant.
-
- Having done the installation of the Kinetics driver, set ethernet and
- internet addresses etc., when I start up NCSA telnet (on a mini-Ethernet
- on which the only other computer is a Lanalyzer in promiscuous mode!!!)
- the following packets go out:-
- 1. arp broadcast with source ip 0.0.0.ff, looking for 0.0.0.7f
- 2. broadcast with type 80f3 (?)
- 3. arp broadcast with source ip 0.0.0.7f, looking for 0.0.0.7f !!!!
-
- These three are repeated immediately (interval of about 3ms) about 20 times,
- making 60 broadcast packets in 200ms!). Then immediately follows
-
- 4. 2 broadcasts type 809b, one after the other, contents not meaningful
- to me.
- 5. 4 broadcasts type 809b at intervals of 400ms, containing "IPGATEWAY".
-
- Then a lot later there are the arps looking for the host that I wanted,
- at decent intervals of 1 or 3 seconds.
-
- These last arps DO have the correct internet source address.
-
- I know that I may not have read the documentation as well as I ought, and
- we may even be missing useful documents, but the above is a bit of a
- mystery to me. Can you help.
-
- I must also admit that I spend my time trying to tell implementers of
- software products that:
-
- a. I like to minimise the number of broadcast packets.
- b. Never broadcast if you can multicast (at least one of the Kinetics
- test programs throws out vast numbers of broadcasts: not your fault).
- c. There is almost never an excuse for high-rate repetition of identical
- broadcasts.
-
- Best regards,
- Mike Gerard
-
- [ Ed Note-
- [ I don't want to sound like I am passing the buck, but I feel obligated
- [ to tell you that the cause of 1,2,3, and 4 are all from the Kinetics
- [ software. In order to exist on the ethernet, they chose some rather
- [ unorthodox methods of addressing their boxes (and machines which run
- [ the SC or SE boxes/cards. Their method includes arping for 0.0.0.x.
- [ Further, the packets of types 80f3 and 809b are AppleTalk encapsulated
- [ in EtherNet headers.

- If there is a long pause in the telnet mailing list as there has been
- recently, we will be throwing in some "feature/bug" updates. These
- will explain some small details which we have been getting questions
- about.
-
- Feature/bug update from NCSA (Mac version):
-
- NCSA Telnet for the Mac version 2.1 has a companion 2.1E which runs over
- EtherTalk on a Mac II with an EtherTalk card. Kinetics will soon be
- providing an EtherTalk driver for their Etherport SE and EtherSC products
- that we have also tested on.
-
- Use 2.1 for AppleTalk, 2.1E if you have EtherTalk.
-
-
- LaserWriter 5.0 bug -
- Upgrading to LW 5.0 drivers will cause "print selection" to produce
- garbage on your printer if there were any blank lines in the selected
- text. Imagewriter printing still works.
-
- We will be able to work around this in later versions, but for now, you
- may want to load a MultiFinder partition with MSWord or TeachText to paste
- into and use it for printing on a LaserWriter.
