I'm looking for documentation similar to this:
http://developer.postgresql.org/docs/postgres/protocol.html
that explains the interbase tcp protocol

For instance, ethereal calls 00000044 opcode (68), a "prepare
statement", which is then followed by, in an example case, 60 bytes
which includes the ascii "select * from customer"

Other examples include: 0000003e = "allocate statement (opcode 62)"
followed by 4 data bytes, 00000028="request info database (opcode
40)" followed by data of 20 bytes.

Basically, what I want is enough information to write a very simple
client that communicates directly to an interbase server on 3050, to
make simple queries. This would be for a platform that I don't have
interbase client libraries.
