Hello guys, I want to do a test with the Dreamcast Modem. I learned about the BlueCrab ppp.h in KallistiOS, and I'm able to make the Modem Dial and also ping an IP. I'd like to know if it is possible to ping a PHP URL using the post method where I'm going to send some parameters, example:

http://www.mytext.com?name=dreamcast&age=21

I'm using this code:

#include <stdio.h>
#include <kos/dbglog.h>

#include <arch/arch.h>

#include <ppp/ppp.h>
#include <kos/net.h>

KOS_INIT_FLAGS(INIT_DEFAULT | INIT_NET);

int main(int argc, char *argv[]) {
int i;

ppp_init();

i = ppp_modem_init("12", 1, NULL);
if(i < 0)
return 0;

ppp_set_login("dream", "cast");
i = ppp_connect();

if(i == -1) {
printf("Link establishment failed!\n");
return 0;
}

printf("Pinging the other side of the link (%d.%d.%d.%d)\n",
net_default_dev->gateway[0], net_default_dev->gateway[1],
net_default_dev->gateway[2], net_default_dev->gateway[3]);

for(i = 0; i < 10; ++i) {
net_icmp_send_echo(net_default_dev, net_default_dev->gateway, 1234, i,
NULL, 0);
thd_sleep(500);
}

printf("Pinging sylverant.net (67.222.144.120)\n");
for(i = 0; i < 10; ++i) {
uint8 addr[4] = { 67, 222, 144, 120 };
net_icmp_send_echo(net_default_dev, addr, 1234, i, NULL, 0);
thd_sleep(500);
}

ppp_shutdown();
return 0;
}

I tried to created a method: https://stackoverflow.com/questions/2207...e-response

But I didn't get it working. Any input or directions would be welcome, thanks a lot.

Thanks a lot Megavolt85, is it possible to ping a URL and send some parameters to a post method?

I want to make a online ranking, so the URL would receive something like:

http://www.mygame.com?name="dreamcast"&score="1000"

I'm going to try to do a post using pure C++ anyway.

Yes I did this one for testing:

https://mcdctest.000webhostapp.com/

If you ping it with some parameters, it will show the new data.

Example:

https://mcdctest.000webhostapp.com?name="Megavolt85"&score="400"

**megavolt85** · 03.03.2021 17:27

https is not a good choice for dreamcast, use only http

EDIT, oh i'm check, http supported

**megavolt85** · 04.03.2021 02:20

I'm sorry, but the network functions via a modem in KOS do not work
work only ping

you can compile example httpd, it's don't work via modem

It's okay, thanks a lot for trying to help me! Do you think I can get it working with the BBA?

Network in KOS doesn't work on BBA too Smile

)) At least on my adapter.
Moreover, it never worked and the author of this code ignores this fact.

I understand!!! That is sad =/ Well, thanks a lot you two Smile
