[PD] TCP/IP communication from the unix server to the Pure Data

Apparently [netclient] on the Pure Data side cannot receive nothing else 
than ; delimited messages.
So the solution for the problem:
*My question is, is there a way to send something other than string 
message to Pure Data, like byte-stream or serialized number stream? Can 
Pure Data receive such messages?*

The solution is to use [tcpclient], it can receive byte-stream data.

Now I have another problem regarding the data read, on how to convert it 
back to usable numbers.

 From my UNIX server I am sending a structure

typedef struct {
     int     var_code;
     int    sample_time;
     int     hr;
     float    hs;
} phy_data;

Sample data might be 2 1000000 51 2000.56

When received and printed  in Pure Data I get output like this:

 >>>: 2 0 0 0 104 34 9 0 51 0 0 0 235 50 48 69

You can notice number 2 and number 51 clearly, I guess the others are 
correct as well. Might be some network inversion of LSB/MSB.

*How can I get these numbers back to a usable format and get them in 
separate variables?
