5.6 Verifying Your Connection 
Start a communication program (HyperTerminal) and place the computer in terminal mode. 
Refer to your computer manual to find out the appropriate commands to do so. 
 
Follow these procedures to verify your installation: 
 
1. Type 
 
    AT [Enter] 
 
    If your system is operating properly, the TA will respond with ‘OK’ message to your 
screen and will wait for the next command. 
 
2.  
Use your communication software to prepare your computer to dial a data call.  
    For example, you can test the data connection under V.110 protocol with the following    
    procedures. 
 
    AT%A2 = 1    ;  Select V.110 communication protocol. 
    ATD 5552121 ;  Where 5552121 is the called party’s telephone number with V.110    
                               protocol setting. 
 
 After ATD5552121 you can see the TX/RX   LED is lighted and then, the ‘CONNECT’ or 
‘NO CARRIER’ message will be displayed. 
 
   CONNECT; Means TA connected with the Called Party. 
   NO CARRIER; Means TA did not connect with the Called Party, may be due to  
   
 
   Called Party busy.
