- Foreign Keymaps
- Ultrix uses trailers by default: warning

- From: timk (Tim Krauskopf)
- Subject: Note about foreign keymaps
-
- A hint for users that want something other than the U.S. Keymap for
- use in NCSA Telnet.
-
- The KCHR resource in NCSA Telnet is there for one reason, to map the
- option key to control as MacTerminal does. If you can live without
- the option key mapped to control, by using the command key, or if you
- have an ADB keyboard, then turn it off.
-
- Turn the mapping off in the preferences dialog (option mapped to control)
- or remove the KCHR resource. You should find that the U.S Keymap is
- not installed. Remember that only ASCII keys are supported by the telnet
- protocol.
-
- Thanks to Gaige for pointing this out, please mail back if this doesn't
- work.

- Subject: Ultrix uses trailers by default: warning
-
- I have recently received some queries about trouble with Ultrix
- configured VAXen and VAXstations. They seem to have started when
- Ultrix was upgraded to 2.0 or 2.2, sometime about then.
-
- After the last query, we discovered that Ultrix is shipped with the
- setting for trailers default ON. NCSA Telnet can't deal with trailers
- and they have questionable benefits for the system, so let's all turn
- them off.
-
- Symptoms:
- 'cat'ing large files will scroll for about 2 packets (512 to 1024
- bytes) and then telnet freezes up. You have to close the connection and
- re-open to get it working again.
-
- Solution for Ultrix users:
- You must be super-user to do this:
- in the file /etc/rc.boot, on the line(s) which apply to your Ethernet
- interfaces, change the ifconfig line:
-
- from: /etc/ifconfig xxxx name
- to: /etc/ifconfig xxxx name -trailers
-
- See 'man ifconfig' for more info.
-
- Trailers are only used on large packets > 512 bytes, so you don't see any
- problems when you log in, only when you cause large amounts of data to
- be transferred. Change all machines at once, they must match in their
- settings for trailers.
