This is a Python tool for controlling CTC 197720 and 197730 relay
cards. There are commands for controlling single relays (set, clear and
toggle) and the port command to read or set all at once.
Chaining boards is supported but not tested. You should issue the init
command to trigger automatic address configuration and use the --address to
send follow-up to a specific board.
Please see ./ctc-relay.py --help and ./ctc-relay.py $command --help for
details.
