I've been trying for the past week to verify that telephony on my teletype
machine (model 33) is functioning properly but the biggest hurdle I am
running into is I have nothing to easily dial into. Everyone I know off hand
either don't have a modem anymore or theirs is a Winmodem which won't work.

There is strong possibility that one of those bridges might not work. As a rule

The Baudot thing sure brings back some memories. I still recall hooking
teletype's up thru KW-7 boxes, and performing ryryryryryryryryr test.
I don't recall enough of the specifics, but it was either
Y = 10101
R = 01010
or reversed.
