Problem getting http data at 256th char

[Slartitorto]

Hi, I have this problem getting http response from my server. After the http header, the server simply responds with a string: %ACK192168002098008008008008192168002001255255255000 This is a mark (“%”), an acknoledgment for the client and four ipaddresses; this string is done by a simple php script. Using the code below, after the mark I get: ACK19216800209800800800800819216800⸮2001255255255000 After some test, I see the junk char is -1 and it occur after 255 char retrieved. Please note that this issue does not occur using the same code but UIPEthernet library

client.print(F("&lip="));
client.print(Ethernet.localIP());
client.println(F(" HTTP/1.1"));
client.print(F("Host: "));
client.println(server_name);
client.println(F("Connection: close"));
client.println();

while(client.connected() && !client.available()) delay(1); //waits for data
if (client.connected() || client.available()) { //connected or data available
  while (client.read() != '%') {}
  for (int i = 0; i < 52; i++) {
    c = client.read();
    Serial.print(c);
  }
  Serial.println();      
}  

} else { Serial.println("connection failed"); //error message if no client connect Serial.println(); } client.stop(); }

test available() before every read(). there can be gaps in data flow.
