Serial Line Communications

[Bryan W. Maxwell]

Hi guys im back. Well i think i have taken care of the routing and such. I 
setup the local rl0(ethernet card) to 192.168.2.1 and in the hosts file i 
setup a slip-gateway as 192.168.2.2. This allowed me to use the command 
arp -s slip-gateway auto pub. This allowed me to ping the 192.168.2.2 side 
of my slip-gateway which is setup like this. slattach -h -l -s 
19200 /dev/cuaa0   ifconfig 192.168.2.2 192.168.2.3 up This is a serial 
line connection to a pic micro controller. Ive run the TD and RD through an 
oscilloscope and dont seem to be getting anything out of them when i try to 
ping 192.168.2.3. Anyone have some good hardware/software tests i can try. 
I have two computers with bsd so i was thinkin maybe a serial line between 
them, any ideas on how to set that up? Thanks in advance, i know this is a 
huge open question to answer but any help would be much appreciated. Thank 
you.
