[GreenKeys] Handling CRs

[Eric NO3M]

Thanks for all the comments.

I got a little ambitious this afternoon following my post earlier and 
starting tearing away at the stunt box.  Its been quite interesting 
pouring over the old bulletins, diagrams, and the W6FFC (Hoff) article 
series that ran in the RTTY Journal from the early 70s.

I basically removed all the switches, function bars, function pawls, and 
associated springs from the stunt box except for slots 1,2,3,4,5,39, and 
40.  All parts are bagged and stored in a box inside the compartment 
below the printer.

Slots 1,2,3,4,5 and 39 were left as-is (4 and 39 is the end-of-line 
auto-CRLF).  Had to adjust the right margin ring on the spacing drum to 
get 73 character auto-CRLF, was doing 78.

I took one of the universal function bars and snapped off tines to make 
another CR function bar.  That was installed in slot 40 replacing the 
original LF function bar.  I moved the original LF bar to slot 30 which 
has a function lever that engages the space suppression bar.

So far, with some limited on-air reception, it is working great.  A 
received CR results in a CR-LF action and a received LF does nothing.  
Clearing out all the other slots also got rid of the multiple blank 
locks keyboard stuff and also restored the shift-H (#) behavior.  
Originally there was space suppression on the (#) character.

Jeff: I look forward to seeing the information you gather about the 
various logger behaviors.  It would be useful to know what to expect, 
hopefully CR=CRLF and LF=null is sufficient.

Jerry: I am not experiencing the double line problem you mentioned by 
putting a CR function bar in slot 40.  The spacing correctly corresponds 
with the single-double LF lever setting.  Thanks for all the information 
regarding the various part numbers and kits.  I'll archive that info for 
sure.
