Transaction ID Meaning and function

[Joe]

Hi all,

I'd like some more info about Transaction IDs used in mbim-network
script as an argument of "--no-open" option of mbimcli.

Could you explain me better why there's need specifying a "$TRID"
transaction id?
I think the answer likely will envolves some basics of MBIM
communication protocol...
Anyway I've not found any documentation regarding... so if you
could give me few more details that would be really appreciated.

Thanks in advance!
See you
