TLV Tag 1

[ForeverCode]

Does anyone know how I would make a TLV tag?
It's suppose to be 2 byes long and its used in AOL's TOC protocol among other things. I cant seem to find any usefull information on how to make it. Im having probs. with the initial signon:
Client To Host:
4 byte FLAP version (1)
2 byte TLV Tag (1)
2 byte Normalized User Name Length
N byte Normalized User Name (NOT null terminated)

TOC:

At the bottom. Any help would be appreciated.

TLV's are used a lot in for example in the GSM std.

Here the TLV is
1 byte for Tag (structure identifier)
1 byte for length (length of data or length of entire struct - don't really remember)
xx bytes for the data included in the structure.

You need a specification from AOL to create the correct structure incl. correct tags.

Have a look at

http://www.etsi.org

for GSM specs.

Cool, thanx. I'll check out that website. I think I was able to get what I was looking for by using htons(). The data I'm generating looks like the stuff I got by packet sniffing GAIM and other Clients. Although I dont understand why yet.
