[rtl] rt_com

[Giorgio Lami]

I'm trying to comunicate via serial port in a RT module.
But looking at the TX bit with the oscilloscope there is no signal.

This is my source:

#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/version.h>
#include <linux/cons.h>
#include <rtl_sched.h>
#include <rtl_fifo.h>
#include <rt_com.h>
#include <rt_comP.h>


#include "common.h"
RT_TASK mytask;

void mainloop(int fifodesc){
        int data=0;
        while(1) {
                data++;
                rtf_put(1, (char *) &data, sizeof(data));
                rt_com_write(0,"prova",5);
                rt_task_wait();
        }
}

int init_module(void)
{

        RTIME now= rt_get_time();

        rtf_create(1,3000);
        rt_com_setup(0,9600,0,1,8);

        rt_task_init(&mytask, mainloop, 1, 3000, 4);

        rt_task_make_periodic(&mytask, now+1000, 25000);

        return 0;
}

void cleanup_module(void)
{
        rt_task_delete(&mytask);
        rtf_destroy(1);
}

The module does work, because I can read from the fifo all data writen, but 
I can't read anything from the serial port.


Ciao Giorgio.
