[PD] tcp connection and raw data

[Federico]

hello list,

I have a I/O device that comunicates with a PC via a TCP connection over 
ethernet.
I would like to use puredata to control it, but I need to send raw 
bytes, and parse responses.

for example, a typical init sequence would be:
0xF0 0xF0 0xF0 0x00 0x02 0x00 ....

it is possible to do this with pure-data native objects?
or externals?
or I should write my own external in C, that implements such protocol, 
and acts as a PD-wrapper for that protocol?

thanks
