How often should I re-transmit un-acknowleged messages?

The simplest thing to do is simply pick a fairly small delay such as one second and stick with it. The problem is that this can congest your network with useless traffic if there is a problem on the lan or on the other machine, and this added traffic may only serve to make the problem worse.
