I'll put the device driver on http://www.freebsd.org/~julian/ but it needs teh eyes of someone who's really at home in the tty system to look at it. I got kinda confused half way through hacking it (from the pty driver) and it shows. basically each pair of minor numbers is a pair and are connected to each other back-to-back. The support for 'select' etc is a bit confused at this stage. also originally I wanted it to shut down the other one (e.g. like loss of carrier) when one gets closed, and for one that is openning to stall waiting for its partner, but it turns out that makes it hard to use with vmware. So I backed that out (which gives a bit more confusion). the screenshot will be there too, (but it's big) also the little script I use to get it all sarteed (trivial).
