Please read the FAQ file that comes with tcsh, particulary section 14
substituting cray with 4.4BSD:
14. On the cray, sometimes the CR/LF mapping gets screwed up.
You are probably logged in to the cray via telnet. Cray's
telnetd implements line mode selection the telnet client
you are using does not implement telnet line mode.
This cause the Cray's telnetd to try to use KLUDGELINEMODE.
You can turn off telnet line mode from the cray side by
doing a "stty -extproc", or you can get the Cray AIC to build
a telnetd without KLUDGELINEMODE, or you can compile
a new telnet client (from the BSD net2 tape), or at least
on the suns use: 'mode character'.
This is definitely not tcsh fault; all the shells that use command line
editing suffer the same way. Try set -o emacs in the bourne shell...
