boa tarde, Preciso de Ajuda com este soquete Que Estou modificando para Receber Dados em ascii e conversor parágrafo hex, o código ESTA ASSIM:

Some pacing to ensure we don't split any incoming data.

sleep (1);

Timeout the socket if it's not talking...

Prevents duplicate connections, confusing the send commands

$loopcount++;
if ($loopcount > 120) return;

#remove any whitespace from ends of string.

$rec = trim($rec);

/ M?DULO IMEI GEN?RICO /

$isGIMEI = true;

}

}

Preciso Que salve em hum Arquivo de log, mas nao deu Certo alguem PODE me Ajudar !!!
