I try to decode the following 3GPP SMS-SUBMIT T-PDU, using gsm_sms dissector: 01000B811192979297F2000010ECF71B2E0E8FD7A076793E0F9FCB But wireshark thinks, that it is downlink tpdu, and decodes is as SMS-SUBMIT-REPORT. Of course, there is a way to encapsulate this T-PDU into some higher-level protocol by adding fake header, and that protocol will call gsm_sms dissector with proper parameter. But for me is interesting, is there a way to put some parameter to text2pcap to make it thinking that this is uplink message? I use text2pcap in the following way: echo "000000 01 00 0B 81 11 92 97 92 97 F2 00 00 10 EC F7 1B 2E 0E 8F D7 A0 76 79 3E 0F 9F CB" > tpdu.txt text2pcap -l 151 tpdu.txt tpdu.pcapng wireshark tpdu.pcapng And I see that it is decoded as SMS-SUBMIT REPORT, i.e. in wrong way. What I am asking is some parameter that can be used with text2pcap allowing to make it thinking that direction is uplink.

use the -D and -n text2pcap options and before the packet dump use:
It will give the following decoding:
