the prompt to start your X-MODEM transfer. 

•  Start the 1kX-MODEM file transfer (send file or upload) by selecting the Transfer / 

 menu item in your terminal emulation (e.g. Hyper Terminal). Select the 

new software and press the Send button.

Idle connection control (Date Transmit Control DTC) is a function integrated in the firm-
ware for monitoring the data transmission in online operation.  
This function prevents the INSYS ISDN TA for remaining online for an unlimited duration 
during a X.25 connection, although no more data is transmitted anymore. 
The function is only valid for the X.31 B channel. 
Any byte sent to the terminal or received by the terminal resets the timer completely 
again and it starts to run again. 
The connection setup takes place if no more data is sent or received and the set time has 
expired completely. 
AT command for idle connection control:

xx seconds to the termination of the connection (xx: 1..255)
