	No, I didn't think that would ellicit any response.

	I would like a copy of your specs for MSTCP.VXD if you manage to
find them.

: Hmm, sounds interesting.  I wonder how much could actually have changed 
: (other than being a 16-bit Prot-Mode interface to a 32-bit Prot-Mode 
: interface (*if* that difference even exists)).

	The 32-bit interface and the 16-bit interface are the same, as one
can find out by dumping the VXD's entry table - the PM and V86 entry
points are the same. I think this is the same for WSOCK2.VXD.

	I think libsocket actually calls the VXD from protected mode - no
16-bit thunks or anything. I think the reason this works is that the VXD
*knows* it's being called from protected mode.

: Current version of WSOCK2.VXD for Win95 does not:
: WSOCK2   VXD        23,203  03-20-98  6:00p WSOCK2.VXD
: WSOCK    VXD        15,547  03-20-98  6:00p WSOCK.VXD

	You misunderstand me WSOCK.VXD from Winsock 1.1 and WSOCK.VXD from
Winsock 2 are the same. It could be that it's not overwritten - doh.

: BTW, is there a new mailing-list for it?  I used to be subscribed to 
: "dossock" but it disappeared.

	Me too. Apparently the list admin's computer crashed and the admin
had no back of the subscriber list. Maybe we should set up another one on
onelist or a similar service?
