     packets are exchanged on UART1; UART0 is still the serial console.

 

+    1. Configure and build the slip-httpd configuration.

+    2. Connect to a Linux box (assuming /dev/ttyS0)

+    3. Reset on the target side / attach SLIP on the Linux side:

+    

+       $ slattach -p slip -s 57600 /dev/ttyS0 &

+ 

+       This should create an interface with a name like sl0. Add -d to

+       get debug output.  In the naming, slN, the N corresponds to the

+       tty device number as in /dev/ttySN.

+

+    4. After turning over the line to the SLIP driver, you must configure

+       the network interface. Again, you do this using the standard

+       ifconfig and route commands. Assume that we have connected to a

+       host PC with address 192.168.0.101 from your target with address

+       10.0.0.2. On the Linux PC you would execute the following as root:

+

+       $ ifconfig sl0 192.168.0.101 pointopoint 10.0.0.2 up -OR?-

+       $ ifconfig sl0 10.0.0.2 pointopoint 192.168.0.101 up

+       $ route add 10.0.0.2 dev sl0

+

+       Assuming the SLIP is attached to device sl0.

+

+    [ NOTE: As of this writing, I actually have not yet successfully         ]

+    [ configured SLIP on Linux.  The above are really just my working notes. ]

+    [ I suspect that I may have the IP address backward for one thing.       ]
