I actually started writing ppp support at one point, so that we could
test using point-to-point connections between UMLs, but the project got
canceled before I got anywhere.

I want the UML to send data out the host's serial port so the UML
process can setup a ppp session to something connected to the hosts
serial port. --not talk to the host.
I know I can run pppd on the host and give the UML a network connect
to it, but I don't want to do the connect that way. I want as much
of the processing as possible to be in a jailed UML.
I gather that I can give the UML the /dev/ttyS0 connection to the
serial port and have the UML pppd connect to ss1, etc.
Thanks,
Mark
