Once the window illustrated has been opened, from the pull-down box choose the name of the installation 
with which you want to be connected. The names entered in the 

Modem index 

during configuration will be 

displayed. Once the choice has been made, the corresponding phone number appears in the box below. 
Click the 

Dial 

button to start the connection procedure. 

At this point the program will instruct the modem to make the call. While waiting, the sliding blue bar of the 
maximum time allowed for making the connection will be seen (1 minute).  The modem called will take the 
line and exchange the usual handshaking messages with the answering modem. At the end of this 
procedure, if everything has been carried out correctly, the PC status bar  will show a message informing the 
user that connection has taken place and the program will switch automatically to the 

Online 

mode.  If any 

errors occur, carefully check the connections and if necessary follow the 

Troubleshooting guide 

given in 

appendix A of this manual. Normally connection is not critical since very common and absolutely standard 
procedures are used. With the 

Break 

button it is possible to block the calling procedure, while 

Hang up 

ends 

a communication already in progress. 
 

Hang up 

This command interrupts a modem connection, closing the telephone line. It is the equivalent of hanging up 
the handset in an ordinary phone call. It is carried out automatically every time you exit the program.
