I'm having difficulty making CTRL-C work in a (putty 0.60) telnet session to the DNS-323.
I.e. pressing CTRL-C does nothing and thus I have to close the session and restart a new one every time something locks up :-(
Why?

It's probably due to stty settings, execute "stty -a" to view them. Depending on which shell you're running you'll have to use different syntaxes to change the settings. Read the man pages.

This is the output:

Code:

# stty -a
speed 38400 baud; rows 61; columns 122;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;
-parenb -parodd cs8 -hupcl -cstopb cread -clocal -crtscts

isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke

The intr character seems to be correct, not?

Ctrl-C works if you're using ssh (dropbear) instead of telnet, ssh is also more secure.

You may be able to get away with ctrl-z instead if ctrl-c is broken, this will stop (pause) the process. and then you can either start it running again in the background with the "bg" command or kill it with ps and kill.

Thanks for the tip. I'll try dropbear then.

I have used the "^Z + kill -9" until now but it is somewhat cumbersome when you're used to ^C.

True - very useful to know though, e.g: if you're running a script at work and it doesn't complete by the time you want to leave, ctrl-z & bg it...
