I needed the same thing recently and someone on this list kindly posted this solution. Put this on both machines in /etc/ppp/options.ttyS0 and then type pppd ttyS0 on both sides. I'm assuming that you are using the first serial port (ttyS0) on both computers here. 'bobspc' will then have two ppp connections running, one to you ISP and one to 'zeos'. ----------------------[ start ]--------------------- /dev/ttyS0 passive persist bsdcomp 15,15 crtscts 115200 asyncmap 0 local lock # # The first ip below is the local ip, the second the remote. # Thus they should be in opposite order on the two machines. bobspc:zeos # # Uncomment this line only on your client machine 'zeos' #defaultroute ------------------------[ end ]--------------------- --Bob
