Description:
	In article <3197@ucbvax.ARPA> Jeff Anton points out:
> ....
> In cbreak mode interupt chars from the terminal will be
> caught and delivered to the script program which is
> not set up to handle them properly.
	An oversight on my part, sorry for the inconvenience.
	I just noticed this yesterday when I used script
	to post some bug reports.
Repeat-by:
	Apply the cbreak fix article <219@ccivax.UUCP> then
	run script. When the interupt or quit character is typed
	script will exit leaving the terminal in cbreak mode
	and -echo. (typing the suspend character will suspend
	script, probably NOT what you wanted)
Fix:
	Turn off all special characters except start/stop.
