The following sequence works. Figuring out why is left as an exercise to
the reader ;-)
Commands:
lrcpc4:~/w/atm/switch/tcp# ./sw_tcp -b -d
lrcpc4:~# atmtcp virtual 1 switch localhost 1 bg
lrcpc4:~# atmtcp virtual 2 switch localhost 2 bg
lrcpc4:~# atmaddr -a 2 +1
lrcpc4:~/w/atm/switch/tcp# atmsigd -b -c 2.conf
lrcpc15:~# atmtcp virtual 1 switch lrcpc4 3 bg
lrcpc15:~# atmaddr -a 1 +2
lrcpc15:~/w/atm/switch/tcp# atmsigd -b -c 1.conf
lrcpc15:~$ ttcp_atm -r -a
lrcpc4:~$ ttcp_atm -t -a +2

The following picture shows a simplified view of the configuration. Note
that the command-line options have been choosen for clarity (and minor
details like the vpci settings in the configuration file have been
omitted) and are not identical with the ones given above.

In order to control the switch with swc, add the line
control <path>
to switch.conf, e.g.
control /var/run/tcpswc
Then invoke swc as follows:
swc <path> show
To add VCs, use add <itf>.<vpi>.<vci> , to add VPs, use add <itf>.<vpi>.?
