Hi Mike,

It sounds me like you are reading the message with a bad format. I suggest
you, for testing pourposes only, to include the read part of the sockect
into a loop that read one byte (in bynary format) until the end of the
message. Once you are able to know which is thespecific message and its
format you could design a better sokect structure. Maybe your problem is a
format problem!

Hope this help,
