Which control signal on a serial cable, indicates that the data set is ready?
(this question provided by simulationexams.com)
| ( | A | ) | | DTR |
 |
| ( | B | ) | | DSR |
|
| ( | C | ) | | RTS |
|
| ( | D | ) | | CTS |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
The most chosen answer was [ C ] :: [ RTS ]
Explanation:
COM1, COM2 on a computer uses a serial cable. The pin
assignments are shown below. The computer acts as a DTE (Data Terminal Equipment)
and the Modem acts as DCE (Data Communication Equipment).
Signal--Name---------DB9 Pin
RX------Received Data--2
TX------Transmitted Data-3
DTR-----Data Terminal Ready--4
GND---- Ground--5
DSR---- Data Set Ready--6
RTS---- Request to Send--7
CTS---- Clear to send--8
Normally, a DTE device connects to a DCE device
with a straight cable. If you want to connect two DTR devices, as you would do
to hook up two computers via the serial line to exchange files, the cable itself
must have cross connections. Such a cable is called a null modem cable.
