*** FREERTOS+TCP IS STILL IN THE LAB (mainly because the FTP and HTTP ***
*** demos have a dependency on FreeRTOS+FAT, which is only in the Labs ***
*** download): ***
*** ***
*** FreeRTOS+TCP is functional and has been used in commercial products ***
*** for some time. Be aware however that we are still refining its ***
*** design, the source code does not yet quite conform to the strict ***
*** coding and style standards mandated by Real Time Engineers ltd., and ***
*** the documentation and testing is not necessarily complete. ***
*** ***
*** PLEASE REPORT EXPERIENCES USING THE SUPPORT RESOURCES FOUND ON THE ***
*** URL: http://www.FreeRTOS.org/contact Active early adopters may, at ***
*** the sole discretion of Real Time Engineers Ltd., be offered versions ***
*** under a license other than that described below. ***
