我使用Indy 的TCP Client去跟一個TCP Server(Linux)溝通，

當我跟IdTCPClient1->Connect()，Server會送18 bytes過來，我想顯示那些字串，但是程式都會hang住，請問Indy Client這部分有接收回傳資料經驗可以幫忙嗎?~

void __fastcall TForm1::Button3Click(TObject *Sender)
{
if(IdTCPClient1->Connected())
{
Memo1->Lines->Add("Connected.");
//Memo1->Lines->Add(IdTCPClient1->ReadString());
IdTCPClient1->ReadFromStack(false, 1, false);
while(IdTCPClient1->InputBuffer->Size > 0)
{
Memo1->Lines->Add(IdTCPClient1->InputBuffer->Size);
AnsiString cmd = IdTCPClient1->ReadLn();
Memo1->Lines->Add(cmd);
}
}

}
