Joe, I have a question on APC-1623. If memory serves me right, Q.2931 uses only Release and Release Complete, i.e. ---- Release ----> <--- Release Complete ---- As I am conscious of the numbers of messages flying around I was wondering if this is sufficient and this would be a better way to go. I've included a picture in the attachment. Pete ============================================= Pete Cordell pete@tech-know-ware.com =============================================
