Adam Dunkels (uIP's author) gave permission for it to be posted to the msp-gcc site if there was interest. In checking the website, it also appears Paul Curtis of Rowley Associates has ported it to the MSP using their Crossworks compiler. http://dunkels.com/adam/uip/ Regards -Bill Knight R O SoftWare
