I don't get it. Why do you say USB? My modem is connected via an Ethenet
cable, not USB. Maybe modem is not the best word for it. Is it gateway?
It's the Portech mv-374.

Hi
That is not possible if you use the GSM as a modem since it talks a
serial protocol (rs232/usb), not ethernet. You might need a serial/usb
sniffer.
wireshark/tcpdump does "sniff" TCP packets.

If you know a tcpdump would do, why don't you use it? On a linux
machine you would do: tcpdump -w FILENAME.pcap -s 0 host
XXX.XXX.XXX.XXX (for example) then use wireshark software to read
the resulting file from the capture.
Once on wireshark you can search for SMPP params, like phone number.
hope this helps.

I have a SIM inside a GSM modem (Portech mv-374), and I need
to see how an incoming SMS packet is formed. A tcpdump would
do, but I don't know how to obtain that. Can someone point me
in the right direction?
