Stale URL for Message Decoding

[jlpoolen]

Line 604 of net_io.c has:

    //
    // SBS BS style output checked against the following reference
    // http://www.homepages.mcb.net/bones/SBS/Article/Barebones42_Socket_Data.htm - seems comprehensive
    //

The URL above does not resolve. However, I have found its successor which is at:

 http://woodair.net/sbs/article/barebones42_socket_data.htm

I recommend line 603 be revised to the URL I found.
