Hello! Makes sense. However I've already decided what my plans are for adding a serial port to mine. As it happens I have here a breakout board for the FT232R (Or FT232RL) device. So that's what I'll be using. As for the other ideas. Time will tell. ----- Gregg C Levine gregg.drw...@gmail.com "This signature fought the Time Wars, time and again." _______________________________________________ ARMedslack mailing list ARMedslack@lists.armedslack.org http://lists.armedslack.org/mailman/listinfo/armedslack
