5.0 AT Command Line Interface
5.1 AT Command Overview
AT Commands can be issued to configure and manage the VIP4G, serial port (Serial), or by TCP/IP
(telnet).
5.1.1 Serial Port
To connect and access the AT Command interface on the VIP4G, a physical connection must be made on
the RS232 DB9 serial port labeled ‘Serial’. A terminal emulation program (Hyperterminal, Tera Term,
ProComm, Putty etc) can then be used to communicate with the VIP4G.
