No. The example doesn't use mySerial and it doesn't print the value of client.read().
If you are going to modify the example, feel free to do a good job.
I was answering to your question about if there were something connecting to the ports.
I thought that maybe it could be a conflict using the Serial for that reason I prove with the SoftwareSerial library. But if I use the normal serial instructions it happens the same.
Arduino Ethernet, the FTDI board and the usb cable using just
char c = client.print() ;
Serial.print(c);
Serial.print(" ");
it prints the strange symbols. Or if I change it for
char c = client.print() ;
Serial.print(client.print());
Serial.print(" ");
it prints the numbers as you said with a space between then.
The strage thing is that when I tried this before no matter with which board it prints the http frame-
