I have a query about the operation of a KSR 33 TTY when
reading paper
tape : does the TTY blindly send the characters read from the tape at 10
cps or is the tape advance and read triggered by a signal from whatever
th TTY is connected to.
Minor niggle... a 'KSR' unit is Keyboard Send/Receive. Ergo: no tape
reader/punch.
Now, an 'ASR' unit on the other hand... B^}
The "standard" TTY unit will operate in the "blind send" mode. You
start
the reader going and the other end had better be able to handle the data
stream. Only mode of operation I've ever seen one a TTY over a modem.
Some installations where the TTY was local to the computer (same
site/direct connect) added a 'reader control' option where the reader was
controlled by the computer. Fairly common on TTYs used with PDP-8 systems.
(my 8/I system uses this control)
