[ECOS] RE: redirect console output to telnet

[Tracy Jones]

Hi - 

I would like to be able to telnet to a port on my ecos box and see the
console output.  I tried a few things

1. Re-direct stdout and stderr - that worked but I got the output from
printf, but not diag_printf

2, Have an accept on port 9000 and do this when I get something on that
port

CYGACC_CALL_IF_SET_CONSOLE_COMM(TCP_CHANNEL);

while (1)

{

            // need to tell if the client has disconnected in some
way...

            sleep(10 * 1000);

}

 
2 actually worked, but I have no way of knowing that the client
disconnected so once I have disconnected I cannot reconnect.


So I tried this
int cur =
CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_CALL_IF_SET_COMM_ID_QUERY_CURRENT
);
 
CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_HAL_VIRTUAL_VECTOR_COMM_CHANNELS)
;

comm = CYGACC_CALL_IF_CONSOLE_PROCS();

       char * buf = new char[512];

       while (1)

       {

		 CYGACC_COMM_IF_READ(*comm, buf, 512);

            ssize_t bytesWritten = send(newfd, buf, 512, 0);

            if (bytesWritten == -1)

            {

                CYGACC_CALL_IF_SET_CONSOLE_COMM(cur);

                break ;

            }

        }

 

This did not work at all.


It seems like what I really want is to port net_io.c from redboot into
my application space but that doesn't work easily.  Does any one have
any other ideas??

Thanks

 
Tracy
