Germany Phone: (6221)516-1 [switchboard] Subject: Ethernet Protocol-access-modes Header-Disclaimer: I don't like my headers either ! hi, I have some questions about Ethernet Protocol access and multicasting. There are three possible Protocol access modes in the DEUNA-Driver available : - NMA$C_ACC_EXE exclusive mode - NMA$C_ACC_SHR Shared default user mode - NMA$C_ACC_LIM Shared with destination The first one is quite clear. But for the last two ones are there some examples to see what they are used for? When does it make sense to use a "default user mode" protocol and when one with the "shared with destination"? The next question is about "multicast address state" (NMA$C_PCLI_MLT). In the PAGESWAPPER of July 1985 (Vol 7, #1) there was an article about "commonly asked XEDRIVER technical questions". For the multicast address state parameter one could read a sentence in the sense of ..."if you want more then 10 multicast adresses (the limit of the hardware) set NMA$C_ PCLI_MLT on". My question is: Could the driver (or someone elese) quick enougth exchange the multicast address table in the DEUNA hardware to enable more than 10 multicast adddresses or what does this parameter really mean?
