Has a bug when receive pdu SMS.

[ru0]

This lib can't receive chinese sms successfully on arduino mini pro . here is my changes.

set pdu mode in GSM3ShieldV1AccessProvider.cpp

else if(ct==5)
{
// 5: Wait IFC OK
if(theGSM3ShieldV1ModemCore.genericParse_rsp(resp))
{
//Delay for SW flow control being active.
theGSM3ShieldV1ModemCore.delayInsideInterrupt(2000);
// 9: SMS pdu Mode
theGSM3ShieldV1ModemCore.setCommandCounter(6);
theGSM3ShieldV1ModemCore.genericCommand_rq(PSTR("AT+CMGF=0"));

change the debug code

void GSM3CircularBuffer::printCharDebug(uint8_t c)
{
Serial.print(" [");Serial.print(c);Serial.print("] ");
if((c>31)&&(c<127))
Serial.print((char)c);
else if(c == 13){
Serial.print('\r');
}
else if(c == 10){
Serial.print('\n');
}else{
Serial.print('%');
Serial.print(c);
Serial.print('%');
}
}
