[GreenKeys] newbie RTTYart questions

[gil smith]

Hi Mike:

Her is one way to connect your pc to your tty:
http://www.baudot.net/tty-connect/

What are you trying to connect together, specifically what pc app and what 
machine?  Programs like RTTYArt and HeavyMetal are designed to talk baudot 
directly to the pc's uart.

thanks,

gil
