Re: [ECOS] httpd running on LWIP over SLIP using eCos.

["David Ho" <davidkwho at gmail dot com>]

Note this configuration is specific to the ARM AT91 target.

The changes of interest are,

1. Serial port is made blocking as opposed to non-blocking.
2. mboxt implementation of mbox is used as opposed to mboxt2.
3. Routed diagnostics to RAM buffer.
4. Serial port buffer size is increased to fit the largest IP packet.
5. Reduced pbuf pool size from 60 to 8.
