The thing most people know in the (computer) world as
a teletype is a
model 33 which really UNIX was unaffected by (other than dealing with
the limited character set) and UNIX didn’t influence. For those with a
model 37 (I had one in my house for a while picked up surplus from Rocky
Flats), you knew of its influence on UNIX. This was a unit that the
line terminator was indeed NEWLINE (^J) rather than carriage return. It
dealt with all the ESC 8 and 9 and the like that nroff put out by
default and th SI/SO to shift from the regular to the greek character
box.
Most importantly for Unix, I would think, the Teletype model 37 had
both uppercase and lowercase capability. Essential for a
case-sensitive environment such as Unix. The model 33 was
uppercase-only.
