3.17.  AT Terminal (TTY) test (V.24 asynchronous) 
 
This feature allows the device to simulate a TTY terminal. In this way you can, for 
instance, send AT commands toward a modem, a terminal adapter or a user’s router 
for configurations and debugs. 
The instrument stores into an internal buffer characters both transmitted and receiver, 
with the possibility to manage and display special characters.
