Hi.

I'm trying to get TCP/IP in dos with Win95.  I'm accessing WSOCK.VXD (through 
int 2f) using djgpp.  I've got several functions to work : Bind, CloseSocket, 
GetSockName, Listen, and Socket.  But when I call Connect or Accept, it just 
returns with an error (ax = 0xffff) and the lights on my modem light up for a 
few seconds.  I know it's trying to connect, but for some reason it fails.

I've also had problems accessing the VxD directly from protected mode.  It 
works just fine in real mode (calling real mode from protected mode with DPMI 
functions, just to go right back into protected mode), but in protected mode, 
int 2f returns a pointer to the vxd call, but it just causes a GPF.  I've tried 
calling it with 16 and 32 bit return address, but neither seem to work.


Thanks,
