App-to-app message exchange

Ruby

I’m probably not using the correct terms, so please excuse…

I need to have a ruby app that loops and keeps a serial port open,
essentially listening every second or so. then I need to send messages
to that serial port app so that it can send outgoing messages, as in a
queue fashion, from other ruby apps.

Is there a gem that can handle cross ruby application message queues?

Drb is one option (not a gem, but std lib). Much more general than
message queues, but it does that too. It will only work between ruby
processes, though.
