http://www.opendax.org/project/issues en http://www.opendax.org/node/88 I need to add a trigger condition for sending master requests. Right now the only conditional request is based on the data that the command is sending. There should be a way to use a different piece of data to determine when to send a request. Possibly one that allows for the module to reset it once the command has been sent. I'm thinking of a boolean tag that another module (or modbus command) could set and then once the request is sent this bit would be reset.

I need to deal with the SIGPIPE in each port thread and stop that thread when it gets one. Then I need to have a generic signal handler for all the threads so that I know where the rest of the signals go. BSD and Linux treat signals quite a bit differently and this will make the module more portable.

It needs to be able to handle master and slave.

I don't know if we'll implement every function code in the specification but there needs to be more than the few that we have done. A complete list is in the TODO file.
