Setting up Telnetd?

[Ian Caddy]

Hi Alan,

We use telnet and shell with RTEMS4.5.0 on a Coldfire 5307 device, so I 
am not sure if this is appropriate to you if you are using the latest RTEMS.

When we configure our device table, we also setup an entry for the size 
of the table:

#define NUMBER_DEVICE_DRIVERS ( (sizeof(Device_drivers) / 
sizeof(rtems_driver_address_table) ) - 1 )

You didn't show it but I assume you have provided this entry (and that 
it is still required for later RTEMS versions).

It sounds like your pty interface is being initialised otherwise the 
telnetd will not call the shell_init with a valid device number.

What was the errno returned at the end of the error message, as that 
will indicate the reason why you couldn't open stdin?

Do you have a debugger that you can step through the code, starting from 
shell_shell (shell.c) and following through the fopen call?

I hope this has provided some help.

regards,

Ian Caddy
