Answer:
Serial communication are connected using 2 types of connector
Explanation:
The two types of connector for serial communication are:
1. Nine pin connector.
2. Twenty five pin connector.
for 9 pin connector we have:
pin 1 = data carrier detect
pin 2= received data
pin 3= transmitted data
pin 4= data terminal ready
pin 5= signal ground
pin 6= data set ready
pin 7= request to send
pin 8= clear to send
pin 9= ring indicator
Here, the minimum number of pins can be pin 2,3 and 5 which are receive, transmit and ground signal to establish a communication without handshaking.
The minimum number of pins actually depend on the type of software we use.
