What are minimum numbers of pins required for serialcommunication? also write
their names?

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.
