Hi Chris,

Thanks for the info, I'll have a look into it.

I think the tcp4u recv function returns the exact number of bytes
received.  I should be able to change peek_sequence to a for loop
to return whatever is in the buffer.

I'll do some more investigation to see if it will effect anything else.

Thanks again,
