Hi SteveI understand that, and I know about the idiosyncrasies of the bulk operations under different implementations.I am asking what would be the best way to, say, implement a READ-SEQ-NO-HANG (for want of a better name) using USOCKET provided primitives; yes I am working with sockets.Reading a byte at a time and listening would work? Any better ideas?I am fooling around as we speak. Any suggestion will be welcome; the only constraint: using USOCKET.CheersWhy does it have to be Usocket ? You'd solve this problem by just using HTTP.--Stelian Ionescu
