That reminds me of some  work involving W6FFC.  He and friends had set
up an autostart net so  they could send messages to unattended receivers.
Irv wasn't universally  popular, so there were some pranksters who would
fire up on the autostart  frequency and send nothing but line feeds, to
unroll all the paper in the  machine.  So Irv came up with some stunt box
hacks to prevent that  kind of vandalism.  I have one of the stunt boxes
somewhere around  here, but don't remember exactly what the treatment was.
Maybe it's in one  of those articles you have.  I remember it involved
having the machine  do a LF when it received CR, which eliminated the
overline problem and also  prevented line feeding on receipt of multiple
line feeds.  And then  there was something to cause only a single line feed
in response to  multiple CRs.
