I'm facing a very strange problem! 
I'm tring to send a string (using the TCP output node) created from an a byte array.
The problem is the following: if I send a byte with a value over 127 I receive an additional byte before of byte in question itself, the value of this byte is fixed and is 192.
Example:
Sending 1,3,2,0,0,184,68, I receive 1,3,2,0,0,194,184,68
Sending 1,3,2,0,0,184,68, I receive 1,3,2,0,0,127,68
Sending 1,3,2,0,0,128,68, I receive 1,3,2,0,0,194,128,68
So... if I send a purely alfanumeric string I will not have any problem, but the problem start when the ASCII value of the byte go over 127.
I tried in many flows and many external TCP server, and also in with a TCP node output and input in the same flow, but the problem still remain.
Please... any help?
This is my flow...
