I have set up a *single* serial to ethernet...
getty on "server"
minicom to "client"
setserial on both
#modify following line to suit
pppd -detach crtscts lock <local IP>:<remote IP> /dev/ttyS3 38400 &
#set up routing - modify to suit
(server)pppd -detach crtscts lock proxyarp <local IP>:<remote IP>
/dev/ttyS3 38400 &
(client)pppd -detach crtscts lock defaultroute <local IP>:<remote IP>
/dev/ttyS3 38400 &
I can't think of any reason why you can't use both ethernet connections
at the same time - but I'm tired ;-)

If it breaks - you get to keep both pieces
