Well if your going this far why not ad real time as an optional alternative? Connect the INVERTED 1 PPS output from a GPS receiver to the RI line in RS232 and use the RI interrupt to make the timing coherent to a rather excellent and free standard available everywhere on this mudball. RI (Ring Indicate) is available on dB-25 Pin 22, and DB-9 Pin 9. Larry VA3LK
