To establish this connection, you need an application that allows you to establish transparent TCP connections, i.e.
without using Telnet or SSH. To do this, this device must have IP access to the device that is going to be monitored.
The most common way to do this is by using a PC and a standard communications program (such as Teraterm).
Syntax
AT*Z32=”<mask>”
Description
This command allows you to configure the mask to limit the IP addresses that may
establish a COM port spy connection with the device.
This command format is similar to an IP address. In this case, the IP address for
the incoming TCP/IP session is “filtered” with this mask and if it doesn’t pass the
filter, the connection is dropped.
Example
AT*Z32=”255.255.255.255”
OK
Syntax
AT*Z34=<port>
Description
This command allows you to configure the number of the port that listens to the
TCP/IP connection petitions, over which the COM port spy connection is estab-
lished.
<port> can take values between 1 and 65535.
Example
AT*Z34=5555
OK
4.4.2.7 Socket 4: GPRS spy socket connection
The purpose of this socket is to allow remote access to the data sequence that is received by the COM port in spy
mode through GPRS. I.e. this socket sends all the data received from the DATA Socket 1 to the central side in ASCII
hexadecimal format. This function is to debug the connection and for investigating breakdowns.
