DC1 & DC3 were used to control the tape reader and DC2 & DC4, the tape
punch. There were some Teletypes that had remote control punches, as
well as readers. Incidentally, I had an ASR 35 connected to my first
computer, an IMSAI 8080. I had it configured so that reading a byte
from the UART would cause the reader to advance another character.
Those old machines had something called a "stunt box", which could
detect various character combinations and either perform some mechanical
funtion or operate a switch. Some of them were quite complex.
Many years ago, I used to overhaul Teletype equipment.
