[GreenKeys] RS232 to TTY Loop Boards

[Ralph Mowery]

That is one of the problems with the leters being subistuted for the whole 
word.  USB in computer terms is totally diffeant and unrelated to USB in 
radio talk.  However many  will receive on either usb or lsb on the receiver 
and then put it to a computer that only has a universal serial bus for the 
input/output to go to the printer. Easy to get confused when USB can mean 
differant things in almost the same sentence.
Such as I want to come out of the receiver in USB, go to the computer and 
come out USB and convert to the printer.

Bet it totally confusing when most hams use lower side band (LSB) instead of 
upper side band (USB) for RTTY and upper sideband for the PSK31 and some 
other sound card modes.

Took me a while to get it in my head about the mark and space signals.
