ASCII reserved four characters, ^Q through ^T, for unspecified device
controls.  The ASR 33 Teletype, which had a built-in paper tape reader and
punch, allowed programmatic control of these devices using these
characters:  ^Q started the reader (assuming paper tape was in it) and ^S
stopped it.  In classic Teletype use, the protocol was bidirectional.  (By
the same token, ^R started the punch, which meant that characters sent to
the terminal were punched as well as printed, and ^T stopped it.

Some DEC OSes used ^T to print a single-line status of the current
process.  I do not know why ^C (end of text, as opposed to ^D which is end
of transmission) took on its present role, but it was definitely already
true in early DEC OSes.
