I had a look at the `ping' program that comes with wfwg 3.11 and it makes calls to 1 or 2 VxD's.
Namely VTCP(0x048A) and VIP(0x0489).  I don't know there interface, but the vxdlist programs I 
have (Andrew Shulman, ddj, ??) lists them as having 1 and 5 rm api's respectively.

I started having a look at them, but haven't got anywhere yet, as they're not listed in RB's 
interrupt list.
