Comm ports on Pc386

[Angelo Fraietta]

I am using the previous snapshot as  do not have networking enabled. I am
trying to open the commport and write some chars (for now). If I just try to
open the port without the code you provided, the file does not open. I assume
it is because the port has to be configured with the code you provided.
However, trying to compile this below, I get a heap of parse errors in
ttr_drv.h.
Is this because of the snapshot or am I doing something wrong here?




#include <tty_drv.h>
#include <console.h>
#include <clockdrv.h>
#include <timerdrv.h>

rtems_driver_address_table Device_drivers[] = {
        CONSOLE_DRIVER_TABLE_ENTRY,
        TTY1_DRIVER_TABLE_ENTRY,
        TTY2_DRIVER_TABLE_ENTRY,
        CLOCK_DRIVER_TABLE_ENTRY,
        {NULL,NULL,NULL,NULL,NULL,NULL},
};

#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_MAXIMUM_TASKS             1
#include <confdefs.h>

rtems_id   Task_id;
rtems_name Task_name;

const char* tty_ports [] =
{
 "/dev/ttyS1",
 "/dev/ttyS2"
};

rtems_task Test_task(
  rtems_task_argument unused
)
{
 FILE* fp = fopen (tty_ports [0], "r+");

 if (!fp)
  {
   printf ("Unable to open %s", tty_ports [0]);
  }
 else
  {
   while (1)
    {
     if (!fputc('t', fp))
      {
       printf ("unable to write to port");
      }
    }
  }

}

Init()
{
 Task_name = rtems_build_name( 'T', 'A', '1', ' ' );
  rtems_status_code status;
  status = rtems_task_create(
    Task_name, 1, RTEMS_MINIMUM_STACK_SIZE * 2, RTEMS_DEFAULT_MODES,
    RTEMS_DEFAULT_ATTRIBUTES, &Task_id
  );
  status = rtems_task_start( &Task_id, Test_task, 1 );
}
