Byte zero contains some flag or identifier (no idea what)
Bytes 1 & 2 contain a 16-bit integer giving the length of the following data
Bytes 3 - n contain the message data, which in this case is a semi-colon delimited string.

int msgLength = buffer[2] << 8 + buffer[1];
char* szWords = new char[msgLength + 1];
strncpy(szWords, buffer + 3, msgLength);
// remainder of code left as an exercise for the reader
// use strtok() to extract each token
//     strcmp() to look for keywords
//
// alternatively use std::string to parse and extract

int msgLength = 80;
            char* szWords = new char[msgLength + 1];
            strncpy(szWords, recvbuf + 3, msgLength);

I need to figure out the length calculation.

            strncpy(szWords, recvbuf + 3, msgLength);

int msgLength = (recvbuf[2] << 8) + recvbuf[1];

#include <iostream>
using namespace std;
