20

PRACK*

DATA ACKNOWLEDGE (Printer) - a low level

 

 

input pulse indicating that the next character

 

 

may be sent.

 

 

 

21

PRPE

PAPER EMPTY (Printer) - out of paper.

 

 

 

22

PRBSY

BUSY (Printer) - an input signal indicating that

 

 

the printer cannot receive data.

 

 

 

23

INPRIME*

INPUT PRIME (Printer) - an output signal that

 

 

clears the printer buffer and initializes the logic.

 

 

 

24

PRSEL

SELECTED (Printer) - an input signal indicating

 

 

that the printer is selected.

 

 

 

25

GND

GROUND

 

 

 

26

PRFAULT*

FAULT (Printer) - an input signal that indicates

 

 

a printer fault condition.

 

 

 

27

GND

GROUND

 

 

 

28

TXD3

TRANSMIT DATA (serial port 3) - data to be

 

 

transmitted is furnished on this line to the

 

 

modem from the terminal.

 

 

 

29

GND

GROUND

 

 

 

30

RXD3

RECEIVE DATA (serial port 3) - data that is

 

 

demodulated from the receive line is presented

 

 

to the terminal by the modem.

 

 

 

31

CTS3

CLEAR TO SEND (serial port 3) - CTS is a

 

 

function supplied to the terminal by the modem,

 

 

and indicates that it is permissible to begin

 

 

transmission of a message. When using a

 

 

modem, CTS follows the off-to-on transition of

 

 

RTS after a time delay.

 

 

 

32

RTS3

REQUEST TO SEND (serial port 3) - RTS is

 

 

supplied by the terminal to the modem when it

 

 

is required to transmit a message. With RTS off,

 

 

the modem carrier remains off. When RTS is

 

 

turned on, the modem immediately turns on the

 

 

carrier.

 

 

 

33

DCD3

DATA CARRIER DETECT (serial port 3) - sent

 

 

by the modem to the terminal to indicate that a

 

 

valid carrier is being received.
