[GreenKeys] Diddle, Real Metal, & Indeterminate Line Length

[gil smith]

Hi George and gang:

The internet audio feed is a very cool idea, and everyone is jumping on 
this new broadcast bandwagon.  For those of you who are now hooking up your 
TUs and real TTY machines, let me just remind you that the TTY-Connect 
board may do just what you need.  Lots of you got these boards, but only a 
couple have been put together that I know of.  So, if your TU has RS-232 
output, get out your soldering iron, and you can:

- select either standard or military TU rs-232 polarity.
- connect george's 60-wpm feed to your TTY at 60-, 66-, 75-, or 100-wpm.
-     (or even your 110-baud ascii M33)
- automatically insert CRLF string, at whatever character position you want
-     (or disable, for rtty art overstriking)
-  automatically filter diddle chars (figs or ltrs),
-     (or disable, if desired)
