Excellent.

Like I said before. Linefeed is a ASCII character, so there is no escape 
sequence or similar that "is the same". A linefeed is a linefeed.
And as I said in my previous post, on *most* terminals, you can generate 
a linefeed by pressing control+J, but it is not 100% guaranteed to work. 
But I would suspect that works. Some terminal (like the VT100) also have 
a specific key labelled "linefeed", which will send a linefeed when 
pressed (just like the key labelled "A" will send an "a" or "A" when 
pressed). Formfeed is another ASCII character, with a value of 12. On 
*most* terminals, you can send that character by pressing control+L.

In which way are they not behaving "properly"?
