Paul,

On Debian testing I get :

octave:1> listen(1234,'debug')
listening on port 1234
trying to accept

"Here I pressed ^c ^c"

Press Control-C again to abort.

"I pressed "^c again"

panic: Interrupt -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete

peter at Home>  

I don't have "octsync.tcl". Should I have it ?.

Peter
