BTRON : I knew that the TCP stack doesn't support multicast, but I create the test code to check the function. I posted a SSDP message, but the tcpdump was bellow X-<

Expat : I comiled the latest library, v1.95.8, using Visuac C++ on WindowsXP, but the following errors occured.

I could search only few same problem from the Internet, and I couldn't find out the solutions. Next, I compiled the previous version, v1.95.1, with no problem and I knew that a call conversion define, XMLCALL, in "expat_external.h" from 1.95.7. Finally I could compile add a compiler flag. Finally, I could compile to disable the define.

FY2004 Exploratory Software Project : IPA, Information-technology Promotion Agency Japan, adopted my development proposal for embedded devices in the project. In my project, I will port my UPnP protocol stack of C++ and create the new small and fast protocol stack only using C to TRON such as BTRON, T-Kernel, ITRON. I have to provide the detail plan and the contract material to IPA from now.

BTRON : I have installed Super Kanji that is a compatible operating system of BTRON to my old note book, PCG-C1. I will buy a new note book for the BTRON because the screen size is small for the development. I am reading the BTRON specification, but it seems that the TCP/IP manager doesn't support the multicast protocol. I might not be able to support the SSDP multicast protocol X-<
