how to activate monitor on specific interface

[Ian Caddy]

Hi Wolfram,

As far as I know the sdtin and stdout are effectively task variables, 
and so what we do is change them in our task.  This works fine for us. 
Here is an example:

rtems_task shell_shell(rtems_task_argument task_argument)
{
    shell_env_t * shell_env =(shell_env_t*) task_argument;
    shell_cmd_t * shell_cmd;
    struct termios term;	
    char * devname;


    devname = shell_env->devname;
    stdin =fopen(devname,"r+");
    setvbuf(stdin,NULL,_IONBF,0); /* Not buffered*/
    stdout=fopen(devname,"r+");
    setvbuf(stdout,NULL,_IONBF,0); /* Not buffered*/
    stderr=fopen(devname,"r+");

The error checking code has been removed for clarity, but you can check 
the returns from the fopens for NULL.

We setup this for each of our interfaces that we use for communications, 
such as some telnet sessions and multiple serial port sessions.

I hope this helps.

regards,

Ian Caddy
