Hi, The command slattach is good for my setup. I had to install a few kernel modules though(slip, slhc etc.) The following steps were used to configure the tcp/ip over serial line: 1)modprobe slip 2) slattach /dev/ttyS0 (COM0 was connected to COM0 with a crossover cable) "sl0" was created. 2) On one system ifconfig sl0 192.168.10.1 pointopoint 192.168.10.2 and on the other ifconfig sl0 192.168.10.2 pointopoint 192.168.10.1 The ping worked fined.
