7. Response Sets 

 

When you send a command to your External Modem, it sends a response to 
your computer. For example, if you type 

AT[Enter]

, the External Modem 

should respond with 

OK

. The External Modem gives out different responses 

for the different tasks that it performs. Communication software use these 
responses to control the flow of the program. The responses that are 
intercepted by the communication program are normally not displayed on 
your computer screen. This section describes the External Modem 
responses returned by the External Modem when you communicate directly 
with the External Modem. 
 
There are five X response sets: 0, 1, 2, 3 and 4. They define certain dialing 
characteristics and how the External Modem handles dial tones and busy 
signals, as described in the following sections. The response classifications 
are designed to meet the requirements for various types of operation and 
application. You can select an X response set by using the Xn command. 
 
Aside from the X response sets, extended responses are also available that 
shows the carrier speed, compression method and the error-correction 
protocol as described in the following table. You can enable the extended 
responses by using the Wn command. 
 
External Modem responses can appear as words or numbers. Your External 
Modem is set up to return word responses. Word responses are followed by 
a carriage return and line feed. If your External Modem is operating under an 
application that handles character strings inefficiently or cannot handle them 
at all, you can use the V0 command to switch to numeric External Modem 
responses. Numeric responses are followed by a carriage return only. 
 
If you do not want to receive External Modem responses at all, you can use 

Q1

 command to disable them. 

 
The following table lists and describes the available response codes, where 
x means that result word/code is available:
