[RDD] Serial Out vs GPIO

We've been using GPIOs on an ACS 8.2 for many years now.  I have 4 GPIs and 4 GPOs connected to a Telos Z/IP One CODEC for use on remote broadcasts.  The GPI do things like "Go live after next event", "Return to automation play", "play a Legal ID", and "Cough/Talkback" from some simple push buttons on at the far end.  The GPO's light up LEDS at the far end for things like "Talkback active", "Will go on Air Next" and "On Air Now" status indications.  It has all worked great, once I dealt with the timing problems in the Rivendell macros where command steps are sometimes skipped over unless you put in some sleep "SL" statements in various places (and all these "places" and timings of them seem to change with each Rivendell update!!!).  We are using a computer with a "real" serial port (not a USB one) however.  We are also using Debian Linux instead of Ubuntu or CentOS.

In my experience there seem to be a lot of RML commands that run fine in external scripts but not directly in RDAirplay.
