    Jan - welcome to the Brave New World of non-machine-generated RTTY 
sigs. What you have just experienced is unfortunately very common - 
because a great many of the available computer-based RTTY programs seem to 
assume the 'receiving' device knows how to automagically insert a CR-LF 
sequence at the end of a 'line' - called "automatic word-wrap" by some. 
The folks who programmed these sometimes put in an option to give a 
"CR-LF" sequence at some point in a line, 66 to 72 chars, but not all do, 
and even fewer users tend to set this option.

  Therefore your (and mine) mechanical RTTY goes right along doing what it 
is told, and if no CR-LF comes along for 1000 charactersw, then it prints 
938 of 'em out on the right side of the platten.  Makes a cool little 
square black hole....

   Later machines had a mechanism to detect this and throw in a CR-LF - 
and, if I  remember correctly, Gil's TTY interface has this built in to 
the code - correct me if I'm wrong, Gil....

   So you have a Navy colored Mod 19...   mines still black crinkle... 
just had it on this evening copying some RTTY, but not very well here at 
the QTH.
