I seem to remember "R-Y" as two letters I could type, and it would make
the
Teletype Machine go from one extreme function to the opposite extreme
function, in the printer and machine and the code functions.
We used to use that as a way to check out if a machine was functioning
properly, as that would put it through all it's steps.
With age, I am wondering if I am right or wrong on it being R-Y.
Was it R-(?) ??

You are correct in the RY. Those two letters are the reverse of each other
and should move the mechanical selectors from one extreme to the other . It
is possible to have the receiver set to the wrong sideband or the
demodulator reverse switch set to the wrong position and you will receive YR
instead of RY. This makes for interesting problems for the new to rtty
person. If a transmission starts off with a line or two of RYs and you are
receiving YRs, when the main body starts up you will receive jumbled
characters.

Altho , this is with the old 5 level code. For ASCII, there is no such
test, tho the closest you can get is the " J * " characters (J, then
upper case 8) as explained by an old boss and teletype mechanic.
and to compound it, the ASCII characters can use 1, or 2 stop bits at
the end of the characters! As info, Jim NN7K

Hi Jim,

Also 1½ stop bits (unless I'm confusing this with RS-232).

When I was in San Diego for Instructor Training, one of my Radioman
buddies told me how their final was given in the form of a box of RTTY
parts that they had to assemble into a complete working machine. He
also suggested that a wandering ET (my rating) would, on occasion (and
hidden from view), donate extra parts to random boxes.

No doubt, the endowed RM striker would mutter some other meaning for
FSK.

If I remember correctly, the Teletype ASR-3x designer
committed suicide.
