Allo i am really trying to connect to my internet service provider (ISP)
using PPP but with no success up to now. Can someone help me solve this
did anybody do this i nned some examples. I tried the examples from
samples folder with no success. Thanks in advance Alain
… i’m looking for the same problem. I’ve looking on how the tcp/ip stak works but no exaple founded.
There are some undocumented or unsupported guides?
Marco
you have a PPP add-on modules!!! That’s right?
only now i’ve doscovered it…
i buyed and now i’m waiting for the code… with the window opened…
tnx
but i’ll not close these tread untill it 'll work 
Marco
ok, i’ve installed the ppp developing add-on but when i scall my PPP activation procedure i get:
While Debugging: Timeout while waiting for response from target."
doh!
I use a LP3500 board with DC 9.52 and ppp lib latest.
I compile and execute in RAM withoux xmem
here is my procedure and configuration:
( it writes “AttivaPPP: tentativo n. 1” ) and crashes!
#define TCPCONFIG 0 //
#define TIMEZONE +1
#define LCP_TIMEOUT 5000
//Use serial port C (IF_PPP2)
#define USE_PPP_SERIAL 0x01
// ECCO COSA POSSO DEBUGGARE CON IL PPP
#define PPP_VERBOSE
//#define PPP_DEBUG
//#define PPPLINK_VERBOSE
//#define PPPLINK_DEBUG
//#define SMTP_VERBOSE
//#define SMTP_DEBUG 1
#define CHAT_VERBOSE
//#define CHAT_DEBUG

#define DIALUP_NAME “”
#define DIALUP_PASSWORD “”
#define DIALUP_NUMBER “#777”
#use “dcrtcp.lib”
/*-=0=-
** connessione **
se co volessimo connettere da zero:
#define DIALUP_SENDEXPECT “ATZ #ok ATDT” DIALUP_NUMBER " #CONNECT ‘’ #ogin: @%0 #word: @%1 ~"
non abbiamo il chat script quindi:
int AttivaPPP ( void ) {
/*-=0=-
Attiva la connessione internet via PPP
ritorna 1 in caso di successo, 0 altrimenti
esegue NTENTATIVIPPP prima di dire che ha fallito
-=0=-*/
static int count;

static unsigned long int tempo, t;
tempo = LeggiRTC();
printf( "AttivaPPP: entro ed inizio a connettermi…
");
Disable_HW_WDT(); // qua posso perdere un bel po di tempo!!!
for(count = 0; count < 3; count++)
{
printf( "AttivaPPP: tentativo n. %d
", count+1);
//configure PPP for dialing in to ISP and bring it up
ifconfig(IF_DEFAULT,

}
if (ifstatus(IF_DEFAULT)) break;
}

hitwd();
if(ifstatus(IF_DEFAULT) == 0 ) {
printf( "AttivaPPP: errore di connessione

return 0;
}
// ok mi sono connesso!
ifconfig(IF_DEFAULT, IFG_IPADDR, &t, IFS_END);

Allo !
I am still confused on how to connect with ISP using PPP2.03 i emailed
customer service and they sent back some usefull info. My problem seem to
be very basic but i still can’t get it done. This is the line of code responsible
for sending and receiving ASCII cars
#define DIALUP_SENDEXPECT1 “ATDT18193212390\r CONNECT ‘’ ogin: xxxxx word: zzzzz PPP”
where xxxxx is my Login(username) and zzzzz is my password. The thing
is i configured the modem on my PC to be linked with com5 serial port
this could be changed to any available port, but when i run the examples for
PPP in the samples folder, the Rabbit running the program doesn’t see
the modem. I disabled flow control and i am only using Tx, Rx, GND, to
communicate with the modem. I’m also using a serial to USB converter
i don’t know if this could create problem since my PC doesn’t have a DB9
Basically it is very straith forward to send a string of command using a
serial port but in this case something is not happening. I would like to know
why the example programs can’t communicate with my modem. Thanks
Allo Ventunocm!
Try to go in project options
—> communications
and take check off of Enable Processor Verification. Ciao! Alain
now i connect…
connect but no connection works example:
int InviaSentenzeRaccolte( char vettore, charbuff ) {
int conta, bl;
unsigned long int tempo;
char *punta;
//static buff[MAXBUFF+1];
hitwd();
if ( tcp_open(&socket,0,atol(DEST),PORT,NULL) == 0L ) {
printf( "InviaSentenzeRaccolte: non sono riuscito a connettermi!
");
return 0;
}
// ok ho iniziato i tentativi di connessione
tempo = LeggiRTC()+TCPTOUT;
while(!sock_established(&socket) && sock_bytesready(&socket)==-1 && LeggiRTC()= tempo ) {
printf( "InviaSentenzeRaccolte: errore chiudendo dolcemente la socket!
");
sock_abort(&socket);
}
return 1;
}
I should send the content of vettore and what i receive i put into buff
but he sad to me that has an error on:
tcp_open(&socket,0,atol(DEST),PORT,NULL)
socket is defined in the general space as:
static tcp_Socket socket;
Hi all, i’ve solved the problem using a Wism GPRS modem
if you want some working fine i’ve buyed from:
http://www.rccitaly.com/Erco-Gener/Prodotti-ErcoGener.htm
If you want refer that i’ve sent to you the adress!
