Reports Chapter 2 - About VT/ANSI Programming The computer sends reports in response to host computer requests. Reports provide identification (type of computer). Two categories of reports are available: primary/ secondary device attributes, and device status reports. Device Attributes (DA) The following table shows the action taken by the computer when it receives primary and secondary device attribute exchanges. During a primary exchange, the host asks for the computer's service class code. The computer responds with "I am a service class 2 computer." During a secondary exchange the computer responds with "I am a VT (identification code of 1) family computer."

Device Status Reports (DSR) This table shows the action taken by the computer when it receives device status report exchanges, when the host computer asks for the general operating status of the computer or printer, or both. If the computer is in printer controller mode, the printer receives the DSR request but cannot answer.
