|
The pins in a serial port are all in one line.
|
|
|
The printer is addressed as a serial number.
|
|
|
Data for the printer is sent serially, one bit at a time
|
|
|
The serial ports are assigned serial numbers by the IEEE

Detailed explanation-1: -In serial communication, data is sent one bit at a time using one signal line, so in order for the receiving side to accurately receive the data, the sending side must know at what speed it is sending each bit.In RS-232C, synchronous communication and asynchronous communication standards have been defined.
Detailed explanation-2: -Most serial ports use between five and eight data bits. Binary data is typically transmitted as eight bits. Text-based data is transmitted as either seven bits or eight bits.
Detailed explanation-3: -Serial hardware sends and receives data as electrical pulses that represent sequential bits. The zeros and ones that carry the information that makes up a byte can be represented in various ways.
Detailed explanation-4: -In serial communication, data is transmitted one bit at a time (Figure 4.20a). Thus if an 8-bit word is to be transmitted, the 8 bits are transmitted one at a time in sequence along a cable.
