I'm used 0x0100007f.  This address worked fine when I called bind(). 
The wsock vxd doesn't have a htons function.  It has the following
functions:

Working		Failed		Not tested
		* Error 0xffff			ACCEPT
*						BIND
*						CLOSESOCKET
		* Error 0xffff			CONNECT
*						GETPEERNAME
*						GETSOCKNAME
				*		GETSOCKOPT
				*		IOCTLSOCKET
*						LISTEN
				*		RECV
				*		SELECT_SETUP
				*		SELECT_CLEANUP
				*		ASYNC_SELECT
				*		SEND
				*		SETSOCKOPT
				*		SHUTDOWN
*						SOCKET

				*		CREATE
				*		CREATE_MULTIPLE
				*		DESTROY
				*		DESTROY_BY_SOCKET
				*		DESTROY_BY_THREAD
				*		SIGNAL
				*		SIGNAL_ALL

				*		CONTROL

				*		REGISTER_POSTMSG

				*		ARECV
				*		ASEND

When connecting, I first called Socket, then Connect.  I tried binding
if before connect, but it didn't make any difference.  When accepting, I
called Socket, Bind, Listen, then Accept.

Also, after I connect to my ISP, bind worked when I gave it my correct
INET address.  It didn't work when I gave it a dummy address.

After I tried connecting, I called getpeername, and it returned with an
error, but it did fill in the inet address corectly.  I've tried
connecting to my ISP's http and ftp servers, and to a http server
running on my computer using 127.0.0.1.

Do you know anyone who has the Win95 DDK?  I think it might have some
information about wsock.vxd.  The information I've gotten is from
wsock.inc, a winsock refrence, and disassembling the vxd.

Thanks, Dan
