I tried that already (got that info from a web site earlier)
Just tried it again BL3 to BL2.  Won't telnet or even ping.

pppd /dev/tthS0 115200 192.168.1.1:192.168.1.2 local crtscts
registered device ppp0
reversed the numbers on the other computer.

Ping 192.168.1.1 (sends to itself in 0.0 ms)
ping 192.168.1.2 56 data bytes   - nothing happens, I hit Ctrl-C
and 100% packet loss

telnet won't work either (with in.telnetd -debug on target computer)

The website said I needed to make a file /etc/ppp/options with things like 
local and crtscts in it.  I will try that next.

Did not help.  On BL3 it just does nothing visible except tell me 56 data 
bytes, on BL2 ping tells me network is unreachable.

Do I need some other sort of packet driver besides ppp?
Another sort of program?
