Actually, a while ago I have implemented a simple link-level protocol for FreeBSD that does allow to do the same easily. It was written for 2.0.5 but if someone does need it (and/or if the core team members will consider the idea appropriate) I can find it in my archives and port to -current. Personally, I think that adding the link-level protocol (if not this then some other) is a Good Thing (tm). -Serge P.S. Does somebody need the loopback pseudo-Ethernet driver ? It's the thing that allows to make network connections from pcemu, and is also very useful for debugging the network code without having a real network (like I do at home). Probably the network support can also be added to doscmd. I have submitted it a while (~1.5 years) ago but it was not committed at this time although the patches for pcemu were.
