Serial Protocols

Serial Protocols

A protocol is a set of instructions that control the way data is

 

transmitted between devices such as a processor and printer. The

 

protocol ensures that the processor does not send information to the

 

printer faster than the data can be processed. By telling the processor

 

when it can receive data, the protocol prevents the printer buffer from

 

overflowing.

 

 

This printer offers a choice of four protocols: XON/XOFF, DTR, RC,

 

and ETX/ACK. The following table gives details. If no particular

 

protocol is recommended, try DTR.

 

Table C–1 Serial protocols

 

 

 

 

Protocol

Description

 

 

 

 

 

 

 

ON/XOFF

When the printer is ready to receive data, it sends

 

(DC1/DC3)

the XON (DC1) code (hex 11). When fewer than

 

 

255 bytes of space remain in the buffer, or when the

 

 

printer is switched offline, the printer sends the

 

 

XOFF (DC3) code (hex 13). The processor must

 

 

stop transmitting data within 255 (63) characters of

 

 

receiving XOFF, or information may be lost.

 

 

 

 

DTR

The DTR signal on interface cable pin 20 controls

 

(hardware)

the flow of data rather than sending a character

 

 

code.

 

 

 

 

RC

Same as DTR except that it uses the Reverse

 

 

Channel signal (pin 11) instead of the Data

 

 

Terminal Ready signal (pin 20).

 

 

 

 

ETX/ACK

This protocol is a little more complicated, but allows

 

 

faster throughput under some conditions. The

 

 

processor adds the End of Text ETX character

 

 

(hex 03) at the end of each block of print data. The

 

 

block, including the ETX character, is usually half

 

 

the printer input buffer, but it can be as large as the

 

 

input buffer.

 

 

The processor must stop transmitting the next block

 

 

of data until it receives the ACK character, or

 

 

information may be lost. Data transmission

 

 

continues until the printer finishes printing two

 

 

blocks, providing high-throughput data

 

 

communication.
