EIA DATA-OUT - This data line is output asynchronous data from
OUTPUT the printer in STX/ETX, STX/ETX/LRCC and X-ON/
X-OFF

- DATA TERMINAL READY - This is a status line
indicating the availability of the printer, i.e.,
that the printer is present and power is ON.
This line goes to the SPACE level on printer
initialization.
- CARRIER DETECT - This is a status line from the
data source indicating that communications capa-
bility is open and conditions the printer to
receive data. When a carrier is detected (com-
munications open), this signal should be at the
SPACE level.
This line is normally strapped at the SPACE
level at all times, but if a user has the
requirement for an active CD, a trace cut will
put this line in service. (See Figure 2-9.)
This pin is not inserted in connector J-2 but
is available and tied back.
READY TO SEND - This signal is normally at the
MARK level and shifts to the SPACE level when
the printer has data to transmit. RTS then
remains at the MARK level for 10 to 68 milli-
seconds nominal after the stop bit of the last
character. The exact delay is a function of
the Baud rate. This pin is not inserted in J2
but is available and tied back.
- SECONDARY READY TO SEND - (PRINTER BUSY Hand-
shake) This signal is a printer status signal
indicating when the printer is ON LINE and
available to accept data. During this time,
the SRTS line is at the SPACE level and shifts
to the'MARK level when the FIFO buffer is full.
It also shifts to the MARK level for any OFF
LINE
conditions, such as Out-of-Paper, etc.
Any character in transit when SRTS goes to the
MARK level will be received and processed.
