[OT Uklid - pocitac

No ja je pouzivam vetsinou jako klienty pro posilani dat na webservery, 
kde data ukladam. Takze takovy GET dotaz pak vypada takto - je to v 
podstate klasicka minimalisticka hlavicka HTTP dotazu:

const rvCR=13;
       rvLF=10;
       socket='192.168.0.116/80';
       host='192.168.0.116';
       skript='/skript.php?';

procedure SendToWeb;
begin
   Usart_Write_Text('ATDT');
   Usart_Write_Text(socket);
   Usart_Write(rvCR);
   Usart_Write_Text('GET ');
   Usart_Write_Text(skript);
   Usart_Write_Text('tep=');
   Usart_Write_Text(txt_teplota);
   Usart_Write_Text('&rh=');
   Usart_Write_Text(txt_rh);
   Usart_Write_Text('&tl=');
   Usart_Write_Text(txt_tlak);
   Usart_Write_Text('&ch1=');
   Usart_Write_Text(txt_ch1);
   Usart_Write_Text(' HTTP/1.1');
   Usart_Write(rvCR);
   Usart_Write(rvLF);
   Usart_Write_Text('Host: ');
   Usart_Write_Text(host);
   Usart_Write(rvCR);
   Usart_Write(rvLF);
   Usart_Write(rvCR);
   Usart_Write(rvLF);
   Usart_Write_Text('ATH');
   Usart_Write(rvCR);
end;

vysledkem je v podstate jako byste v browseru poslal neco takoveho:

http://192.168.0.116/skript.php?tep=5923&rh=2110&tl=59000&ch1=45000
