Description
Data entered from the keyboard
on the terminal is sent to the
system unit for translation and
then sent back to the display
screen. Sometimes called
conversational mode .
Uses the 9600 bps (bits per
second) line speed to
communicate with the system
unit.
Selects eight bits as a data word
length (byte).
Does not add a parity bit and is
used together with the word
length attribute to form the 8-bit
data word (byte).
Places a bit after a data word
(byte).
Selects the carriage return (CR)
character as the line turnaround
character.
Uses the EIA-232 interface
protocol.
Uses the 'permanent request to
send' (IPRTS) signal to
communicate with system unit.
The terminal sends a break signal
to the system unit within 500 ms
after the Break key is pressed.
Trailing null characters are not
sent to the system unit.
Trailing null characters are sent to
the system unit.
The terminal waits for 100 ms for
the system unit to respond.
