After some attempt it seams to me that
multipart/form-data in NET+OS CGI pages is not supported?
strcpy(buffer, "");
strcat(buffer, "");
strcat(buffer, "");
strcat(buffer, "");
strcat(buffer, "");
strcat(buffer, "");
strcat(buffer, "");
when submitted the RpExternalCgi() is not called and no page can be returned
