Setting up Telnetd?

[Ian Caddy]

Hi Alan,

I just checked in our system and dname provides no devices either.

If you have the monitor running you can try the following command:

ls /dev

It should show the list of devices that have been installed on your 
system.  In our system, we have pty0 through to pty9 for the telnet drivers.

When you said you checkd errno, is that the actual variable errno, or 
was it the value returned by the fopen call.  If it was the value 
returned by the fopen call, there is another global variable called 
"errno" which should have a proper error number in it.

I think you are going to have to debug through the fopen call to get 
more information.

Sorry I can't be more help.

regards,

Ian Caddy
